Original Abstract

A novel square wave generator (relaxation oscillator) with controllable frequency is described. It employs two universal current conveyors (UCC) and grounded passive elements. The generator includes integrator with two integration capacitors that alternate in charging which results in linear and precise control of frequency by voltage. New implementation of UCC with attractive properties in CMOS 0.18 um technology is also presented. Computer simulations in PSpice environment confirm the theoretical assumptions.
