Design of Configurable Analog Block-Based Oscillator and Possible Applications

Abstract

This article introduces a configurable analog block with wide functionality which is then used for designing a new sinusoidal signal generator with three outputs. The circuit uses three current feedback operational amplifiers and provides control over the frequency of oscillation independent of condition of oscillation. The new circuit is experimentally tested using AD844 ICs and also simulated using capture CIS tool. Both experimental and simulation results have good agreement. Possible applications are suggested, and one such application is demonstrated in generation of square and triangular waveforms.
