Abstract

See full text

An injection-locked phase-locked loop (ILPLL) circuit includes a delay-locked loop (DLL) and an ILPLL. The DLL is configured to generate a DLL clock by performing a delay-locked operation on a reference clock. The ILPLL includes a voltage-controlled oscillator (VCO), and is configured to generate an output clock by performing an injection synchronous phase-locked operation on the reference clock. The DLL clock is injected into the VCO as an injection clock of the VCO.
