SYSTEM AND METHOD FOR FAST-CONVERGING DIGITAL-TO-TIME CONVERTER (DTC) GAIN CALIBRATION FOR DTC-BASED ANALOG FRACTIONAL-N PHASE LOCK LOOP (PLL)

摘要

A system and method for fast converging gain calibration for phase lock loops (PLL) are herein disclosed. According to one embodiment, a method includes receiving, with a voltage generation circuit, an input value representing a difference between a sampled voltage and a reference voltage, and adjusting, with the voltage generation circuit, the reference voltage by generating a voltage output based on the difference represented by the input value.
