Abstract

A sinusoidal oscillator using two capacitors and three operational transconductance amplifiers (OTAs) is presented. Taking the aid of single-ended OTA, the current-mode sinusoidal oscillator circuit in parts a simple circuitry, that has been stated to be highly suitable for implementation of integrated circuit which in turn use grounded capacitors. The condition of oscillation (CO) and frequency of oscillation (FO) of the same circuit can be set orthogonally. The sinusoidal oscillator is mainly implemented in communication systems, instrumentation programs, measurement devices, and signal processing. The mathematical derivations thus obtained in the circuit can be verified with cadence using model parameters of 180 nm technology process. However, the results arrived have demonstrated excellent agreement with the theoretical values.
