Abstract

In the design of VLSI circuits and systems the need frequently arises for signals having prescribed standard waveforms with specified characteristics like amplitude, frequency and duty cycle. These stand- ard waveforms, which include sinusoidal, square, tri- angular, pulse, and etc., can be generated in Signal Generators. A ring oscillator with adjustable fre- quency and duty cycle is a basic building block for various types of Signal Generators.
