Abstract
According to at least one example embodiment, a method and corresponding system for calibrating an amplifier offset include applying an input value to both input leads of an amplifier. The amplifier includes one or more digital-to-analog converters (DACs) used to calibrate an offset of the amplifier. A digital value, provided as input to the DAC, is updated over a number of iterations, by a control logic coupled to the amplifier, based on an output of the amplifier. A final value of the digital value being updated, e.g., associated with the last iteration, is employed as input to the DAC of the one or more DACs in the amplifier for calibrating the offset of the amplifier during a data reception phase.
