Dual-Mode Sinusoidal Quadrature Oscillator with Single CCCTA and Grounded Capacitors

Worapong Tangsrirat

Abstract


In this work, a sinusoidal quadrature oscillator which simultaneously generates voltage and current signal outputs is proposed.  It contains only a single current-controlled conveyor transconductance amplifier (CCCTA) and two grounded capacitors.  The proposed oscillator has the advantage features of resistorless structure realization, electronic frequency control, availability of two explicit voltage and current quadrature outputs, and low sensitivity figure.  Moreover, the parasitic elements existing at the CCCTA terminals are taken into account.  The performance of the proposed oscillator circuit was verified using PSPICE simulation with acceptable results.

Keywords
