Realization of Colpitts Oscillator using second generation current controlled current conveyor

Abstract

An inductor-less tunable Colpitts oscillator using second generation current controlled current conveyor (CCCII) is implemented. The circuit uses a CCCII and three grounded capacitors. The passive inductor has been replaced by an active inductor [14] connected to the ground. Thus the absence of external resistor and an inductor in the circuit makes it more complacent for IC Design. The frequency of oscillation can easily be electronically adjusted. The PSPICE simulation results have been deduced. The theoretical results are verified with the parameters of BJT PR100N (PNP) and NR100N (NPN) using PSPICE simulation tool.
