Abstract

A receiver for a serial data link, including an analog front end (AFE) including a continuous-time linear equalizer (CTLE) configured to receive an input signal from a transmitter, the CTLE including a first output node; a second output node; a plurality of programmable tail current sources configured to adjust a direct current (DC) offset between the first output node and the second output node; and a calibration circuit including: a slicer configured to output a difference between an average of a first output voltage corresponding to the first output node and an average of a second output voltage corresponding to the second output node; and a calibration counter configured to increment or decrement an offset count based on the difference, wherein the plurality of programmable tail current sources are adjusted based on a value of the offset count.
