Abstract
Acurrent controlled sinusoidal voltage-mode quadrature oscillator circuit is presentedherewhich has employed three second-generation current-controlled-conveyors (CCCIIs) and two grounded capacitors(GCs). The condition of oscillation (CO) and frequency of oscillation (FO) of the proposed circuit are uncoupled and can be electronically controllable through an external dc bias current of CCCII. Sensitivities of active and passive elements are very low and the voltage outputs which are in 90ophase difference have high output impedances. Moreover, if apply the input at terminal Y of CCCII-03 it behaves as biquad filter which produce the band-pass (BP) and low-pass (LP) responses instantaneously and it have high input impedance which is very useful in cascading. The PSPICE simulation resultsverify the workability of the oscillator and filter circuit.
