Abstract
Systems and methods for providing offset calibration for low power and high performance receivers are described herein. In one embodiment, a method for offset calibration comprises inputting a first voltage to a first input of a sample latch, and inputting a second voltage and an offset-cancellation voltage to a second input of the sample latch. The method also comprises adjusting the offset-cancellation voltage, observing an output of the sample latch as the offset-cancellation voltage is adjusted, and recording a value of the offset-cancellation voltage at which a metastable state is observed at the output of the sample latch. The method may be performed for each one of a plurality of different voltage levels for the first voltage to determine an offset-cancellation voltage for each one of the voltage levels.
