An examination of the technical literature on grounded-capacitor (GC) single resistance controlled oscillators (SRCO) has revealed that no GC-SRCO has so far been published which uses only a single active building block (ABB), only two GCs and provides a current mode (CM) output with simple design equations and unconstrained tuning law. The authors not only introduce such a circuit which uses a single ABB called a ‘differential voltage complementary current conveyor’ (DVCCC) but also indicate that a DVCCC is a versatile building block for realising SRCOs. The feasibility of the proposed formulation has been verified in PSPICE using a CMOS implementation of the DVCCC.
