Abstract
The present invention pertains to a high speed duty cycle correction and double to single ended conversion circuit for PLL, comprising a reshaper stage, a single-edge detection circuit and a duty cycle restorer. The present invention introduces a way to convert double-ended output of PLL VCO into single-ended signal and adjust duty cycle of PLL VCO's output waveform by 50%, so that the circuit can output single ended clock signal with 50% duty cycle.
