Simple current-mode sinusoidal oscillator using single CCCCTA and grounded capacitors

Abstract

This article presented current-mode sinusoidal oscillator using CCCCTA. The proposed circuit is very simple comprise of single CCCCTA and has 2 grounded capacitors without external passive resistor. It is suitable for integrated circuit implementation. Furthermore, the proposed circuit can be electrically tuned for oscillation condition and frequency. The output current is high impedances which is easy for driving or cascading to load. The PSPICE simulation is used to verify the performance of the proposed circuit. The simulation results of proposed circuit are accordance with the theoretical anticipation.
