Abstract
An injection-locked phase-locked loop (ILPLL) with a self-aligned injection window is disclosed. In the ILPLL, a phase detector is provided to detect a phase difference between a pair of differential terminals of an injection-locked voltage-controlled oscillator (ILVCO) of the ILPLL. According to the detection, the phase detector generates a control signal, to align an oscillation output, generated from the pair of differential terminals of the ILVCO, with an injection pulse utilized in the ILVCO.
