Abstract

This paper describes the design technique and application of a wide band voltage controlled oscillator. The voltage controlled oscillator is an active device which is capable of generating frequencies over the range of three decades. The lowest three decades range is 15HZ to 15KHZ, and the highest three decades range is lOOHZ to lOOKHZ. The wide band voltage controlled oscillator is composed of an integrator followed by an inverting Schmitt trigger and a wave shaping circuit. The frequency of oscillation changes linearly as the input voltage changes while maintaining constant output voltage. An experimental circuit of the oscillator was tested with excellent results. Active filters, low pass, high pass, band pass, and band reject, were designed and tested by the wide band voltage controlled oscillator with excellent results.
