A Low-Jitter and Fractional-Resolution Injection-Locked Clock Multiplier Using a DLL-Based Real-Time PVT Calibrator With Replica-Delay Cells.
IEEE Journal of Solid-State Circuits(2016)
摘要
A low-jitter and fractional-resolution injection-locked clock multiplier (ILCM) with a delay-locked-loop (DLL)-based process-voltage-temperature (PVT)-calibrator is proposed. The ring-type voltage-controlled oscillator (VCO) and the voltage-controlled delay line (VCDL) of the DLL consist of identical delay cells, and they share the same control voltage. Thus, by changing the ratio between the numb...
