A new structure for a microstrip patch antenna fabricated on a highly lossy and thin FR4 substrate is presented. Elevated radiating edges of the metallic patch with notches as inductive loading form the patch antenna. This structure effectively reduces the dielectric loss and enhances the radiation efficiency. The proposed antenna has been designed and tested at 3.1 GHz as an example. It showed increased radiation power levels of more than 3 dB in both E- and H-plane radiation patterns when compared with those of a conventional planar patch antenna, indicating enhanced radiation efficiency. - Author(s): D.S.

A small internal ceramic chip antenna for IMT-2000 handsets is investigated experimentally and numerically. It has a bandwidth of about 14%, measured gain of 1.3 dBi, and an omnidirectional radiation pattern similar to that of a monopole antenna. These features make the proposed antenna suitable for handset applications.

A novel digital frequency tuning technique is presented for integrated active RC filters. Instead of varying the values of the capacitors or resistors as in traditional approaches, the proposed technique achieves frequency tuning by dividing the currents that flow from resistors to virtual grounds. Current division is performed through a digitally programmable current division network added at each virtual ground. The technique features compact size, wide tuning range and high linearity. Transistor level simulation results are presented to demonstrate the technique. - Author(s): E.K. Chua and K.Y. See

A novel pipelined recursive modified Euclidean (ME) algorithm block for the low-complexity, high-speed Reed–Solomon (RS) decoder is presented. The deeply pipelined recursive structure enables implementation of a significantly low-complexity ME algorithm block with much improved clock frequency. The low-complexity, high-speed RS decoder using the pipelined recursive ME algorithm block has been implemented in 0.13 µm CMOS technology with a supply voltage of 1.1 V. The results show that it has significantly low hardware complexity and a high data processing rate of 6.16 Gbit/s. - Author(s): T. Olsson and P. Nilsson

A fully integrated clock generator with behaviour similar to a PLL is proposed. A free-running ring oscillator is used as internal clock and the output clock is generated using two counters. The clock generator is described in synthesisable VHDL-code and can therefore easily be made from standard cells found in any commercial standard CMOS cell library.

Amplification of a 1 ps pulse train in a 22.7 cm Bismuth oxide (Bi2O3)-based erbium doped fibre amplifier (EDFA) is reported. An amplification bandwidth of 80 nm, from 1520 to 1600 nm is demonstrated. Because of the short length, amplification of picosecond pulses is achieved without pulse broadening over a wide wavelength range. - Author(s): M. Tani and S. Yamashita

A novel image compression scheme based on moment preserving block truncation coding (MPBTC) is introduced. To reduce the bit rate of the traditional MPBTC scheme, the block search order coding technique is employed to exploit the similarity among neighbouring image blocks. In addition, smooth blocks and complex blocks are processed using different methods. Experimental results show that the proposed scheme provides good image quality at a low bit rate. - Author(s): Y.

Ma and Chen have proposed an authenticated encryption scheme with public verifiability. The scheme claims that the TTP can publicly verify the sender's signature without running a zero knowledge proof protocol. The problem in verification which causes the TTP to reject a valid signature with non-negligible probability is pointed out.

A digital duty cycle correction circuit with a fixed-delay rising-edge output is proposed for use in applications with the multi-phase clock and the standby mode. Two integrators are used in the duty cycle detector to eliminate the effect of reference voltage variations. The output duty cycle is adjusted to 50±0.25% throughout the input duty cycle range from 20% to 80% at the frequency of 1.25 GHz. 0.18 µm CMOS technology is used in this work.

Experimental results derived from a prototype show that the proposed predistorter can suppress the adjacent channel interference up to 12 dB compared to the conventional predistorter with a single lookup table. - Author(s): Moon-Su Yang ; Seung-Min Oh ; Sang-Gug Lee

A novel fully differential frequency doubler is proposed based on CMOS technology, where a stacked push–push configuration is used to generate differential output. Compared to previously reported doublers, the proposed topology has advantages in power dissipation, fundamental frequency rejection, and simplicity. By utilising the proposed doubler, a low power direct-conversion up-mixer is designed for 900 MHz applications. The fabricated up-mixer shows 5.5 dB of power conversion gain and 7.5 dBm of output IP3, while dissipating total current of 4.5 mA from 1.25 V supply. - Author(s): E. Rubiola ; E. Salik ; Nan Yu ; L.

Measuring the phase fluctuation between a pair of low-power microwave signals, the signals must be amplified before detection. In such cases the phase noise of the amplifier pair is the main cause of 1/f residual noise. A new scheme is proposed that makes amplification possible while rejecting the 1/f (flicker) noise of the two amplifiers in real time. The first prototype, compared to a traditional saturated mixer system under the same conditions, shows a 24 dB noise reduction in the 1/f region.

It is known that the performance of a SOVA (soft output Viterbi algorithm) turbo decoder can be improved, as the extrinsic information that is produced at its output is over-optimistic. A new parameter associated with the branch metrics calculation in the standard Viterbi algorithm is introduced that affects the turbo code performance. Different parameter values show a simulation improvement in the AWGN channel as well as in an uncorrelated Rayleigh fading channel. By choosing the best value of this parameter, a coding gain improvement of 0.25 dB at BER of 10−5 is achieved compared to existing schemes. - Author(s): Minying Sun ; Yuan Li ; Sumei Sun

Bit-interleaved turbo-coded modulation is more sensitive to signal-to-noise ratio (SNR) overestimation than turbo code with BPSK. An explanation is given from the effect of SNR mismatch on bit-metric generation, which consequently affects the log-MAP turbo-decoding algorithm.

A novel wavelength assignment method for a WDM ring is proposed. The new method can easily assign each wavelength directly and visually to specific connections on an N-node ring graph without the aid of any table or matrix or computer. A simple explicit formula for determining the assigned wavelength index for any node-pair connection is also given. The presented WLA method is more attractive in many aspects than other wavelength assignment methods that have been reported previously for a WDM ring.

A digital pulse width modulation controller is proposed for DC–DC converters. Most conventional digital controllers have required analogue-to-digital converters (ADCs). However, because of the significant power consumption of the ADC, as well as the design time and silicon area, use of digital controllers for battery-operated systems has been limited. To overcome the disadvantages of ADC, a simple but effective deadzone comparator is proposed. - Author(s): F.J. Marín ; F. García-Lagos ; G. Joya ; F. Sandoval

An argon implanted polysilicon thin-film resistor is proposed to raise the sheet resistance and preserve the original electrical characteristics of a resistor for high voltage CMOS technology applications. The experiment results indicate the resistance can be raised by almost two times in magnitude while the voltage coefficient of resistance (VCR) and temperature coefficient of resistance (TCR) are shifted by only 7% and 11% at maximum, respectively. The technology offers potential applications for enhancing flexible circuit design in high voltage CMOS technology. - Author(s): J.L. Pan ; J.E. McManis ; L. Grober ; J.M. Woodall

The influence of annealed ohmic contact metals on the polarisation of the AlGaN barrier layer has been investigated by the Schottky contacts on the AlGaN/GaN HFET structure. The analysed result shows that annealed ohmic contact metals weaken the polarisation of the AlGaN barrier layer. When ohmic contact metals are close to Schottky contact metals, the weakened polarisation decreases the 2DEG sheet carrier concentration in the channel. - Author(s): Il-Yong Park ; Sang-Gi Kim ; Jin-Gun Koo ; Jongdae Kim

A solution to the problem of charge being trapped on the gate of a floating gate MOS transistor during fabrication is presented. The solution does not alter the floating nature of the gate of the device since it does not use any kind of active or passive device to get rid of the accumulated charge. In addition, it does not require any post-processing techniques such as exposure to UV light and does not require any extra masks. - Author(s): J. Ramos and M. Steyaert

A novel blind channel estimation algorithm is proposed for the MIMO-OFDM system based on second-order-statistics. The main idea is to take advantage of the frequency transform and channel autocorrelation characteristics to reduce the computation and make it possible to accomplish the estimation in only one or two symbols. Results show that performance of this new method is promising. - Author(s): I. Santamaría

The design of linear-phase FIR filters is formulated within the support vector regression (SVR) framework. A simple design example shows that, for a given filter order, the proposed SVR technique yields slightly lower passband and stopband ripples than a minimax approach. - Author(s): Zixue Zhao and Gang Li

Based on a polynomial operator approach a new structure for two-dimensional (2-D) digital filters is derived. This is a sparse structure and has the degrees of freedom to reduce the roundoff noise gain. A numerical example is given, which shows that the optimised structure can even surpass the classical optimal roundoff noise realisation. - Author(s): M. Vucic and G. Molnar

A measure for phase linearity based on distortion in the time domain is proposed. The distortion is defined as asymmetry of the system's response to the ideal band-limited signal. The proposed measure is suitable for system comparison, as well as for filter and phase equaliser design.
