Abstract

In this paper a voltage mode third order quadrature oscillator is proposed. The proposed filter is suitable for MOS-C implementation making oscillation frequency electronically tunable. The non-ideality analysis of the circuit is also given and for high frequency applications self compensation can be used. PSPICE simulations have been included to demonstrate the workability of the proposed quadrature oscillator. Simulations are carried out using 0.5 im CMOS process parameters provided by MOSIS (AGILENT).
