Abstract
An object is to keep the oscillation gain nearly constant and attain an oscillation frequency with high stability and low jitter. A voltage controlled oscillator circuit (VCO) is constructed by a VCO control circuit and a ring oscillator. The VCO control circuit has two input terminals (n input, w input). The VC control circuit multiplies the n input by the w input, and outputs a control signal (PMOS n input, NMOS n input) obtained by adding the result of multiplication to the n input. The ring oscillator is constructed by delay circuits of an odd number of stages serially connected.
