Abstract: - This review paper presents comparative study of various multiphase sinusoidal oscillators. Special reference is given to CFOA based oscillator which has high noise immunity, low distortion, relatively large slew rate, extended bandwidth, low sensitivity, low power consumption, greater precision and reliability with respect to active and passive circuit components. The purpose of this paper is to review two circuit configurations for realizing a single-resistance-controlled sinusoidal equi-amplitude quadrature oscillator based on CFOAs. The first circuit uses two CFOAs and second circuit employs three CFOAs. Both the circuits uses grounded passive elements, thus suitable for CMOS implementation. Condition for equal amplitude for quadrature phase is provided and verified by PSPICE simulation results.
