Active-Only Sinusoidal Oscillator with Electronically-Tunable Fully-Uncoupled Frequency and Condition of Oscillation

Abstract

A new active-only sinusoidal oscillator is presented. The oscillator circuit uses two internally compensated operational amplifiers, two plus-type second-generation current conveyors and three operational transconductance amplifiers. The proposed circuit enjoys the attractive features of totally uncoupled frequency and condition of oscillation, low sensitivities, electronic tunability and integratability.
