Abstract
A method of phase detection includes receiving a reference clock and an input clock having a first input signal and a second input; sampling the first input signal and the second input signal into a first sample and a second sample; converting the first sample and the second sample into a first current and a second current; using a regulated current mirror to convert the first current into the third current; using a first current steering network to steer the second current into either a fourth current or a fifth current in accordance with a pulse signal; using a second current steering network to steer the third current into either a sixth current or a seventh current; connecting a lowpass filter to the output node to establish an output voltage and a lowpass-filtered voltage; and forcing the standby voltage to be equal to the lowpass-filtered voltage using a unity-gain buffer.
