Abstract
A phase locked loop circuit includes a phase detector and an oscillator associated therewith, and a voltage-to-current converter for providing that lag signals sent thereto from the phase detector provide increased signal to the oscillator, and lead signals sent thereto from the phase detector provide decreased signal to the oscillator.
