Abstract
A voltage controlled oscillator (VCO) generates a 50% duty cycle clock. The 50% duty cycle clock is derived directly from the operating frequency of the VCO thereby abating the need for the VCO to operate at twice the desired clock frequency. This allows the VCO to be utilized in high frequency phase-locked loop systems.
