Systems and Arrangements to Provide Input Offset Voltage Compensation

摘要

In one embodiment a method is disclosed that includes applying a series of voltages to an input of an offset evaluation latch, detecting an offset voltage from the offset evaluation latch in response to the application of the series of voltages, and applying an offset compensation voltage to the input of a plurality of sampling latch in response to the detected offset voltage. In some embodiments a digital value can be assigned to the applied offset voltage. When the offset voltage is determined, it can be applied to a plurality sampling latches and a data stream can be received and clock and data recovery can be performed.
