Minimum Component Based Sinusoidal Oscillator Using Single OTRA

Abstract

In this paper a new Operational transresistance amplifier (OTRA) based sinusoidal oscillator is proposed. It uses two resistors, two capacitors and a single OTRA. Sensitivity analysis and non-ideality analysis behavior of OTRA on oscillator operation is also investigated. The proposed oscillator circuit is designed using PSPICE simulation and 0.18µm AGILENT CMOS process parameters. PSPICE simulation results agree well with the theoretical analysis of the proposed circuit.
