VOLTAGE CONTROLLED OSCILLATOR

摘要

A voltage controlled oscillator according to the invention is composed of a plurality of delay elements connected in series, the delay circuit for delaying the input signal; Voltage generating circuit for generating a stable voltage level regardless of supply voltage, temperature and process variation and; Hayeoseo use of the voltage as a power source, includes a current source for supplying a variable current as possible to adjust the delay time of each delay element following the temperature change in the delay elements.
