An updated version of a 1985 tutorial paper on active filters using operational transconductance amplifiers (OTAs) is presented. The integrated circuit issues involved in active filters (using CMOS transconductance amplifiers) and the progress in this field in the last 15 years is addressed. CMOS transconductance amplifiers, nonlinearised and linearised, as well as frequency limitations and dynamic range considerations are reviewed. OTA-C filter architectures, current-mode filters, and other potential applications of transconductance amplifiers are discussed.

Inspec keywords: linearisation techniques; active filters; CMOS analogue integrated circuits; current-mode circuits; operational amplifiers

Other keywords: OTA-C filter architectures; linearized type; frequency limitations; operational transconductance amplifiers; CMOS transconductance amplifiers; CMOS OTA; integrated circuit; amplifier architectures; current-mode filters; dynamic range; nonlinearized type; active filters
