Abstract :
A simple state-variable synthesis approach has been presented which makes it possible to evolve current feedback op-amp (CFOA)-based single-resistance-controlled oscillators (SRCO) systematically. Synthesised SRCOs possess several novel features and their workability has been confirmed experimentally as well as through SPICE simulations using commercially available AD844 CFOAs
