Abstract
A circuit includes a receiver coupled to an input node and includes a transimpedance amplifier (TIA). The input node is to be coupled to a transmitter over a channel. Calibration circuitry is coupled to the input node and to modify a resistance of a feedback resistor of the receiver by applying a plurality of control values. The calibration circuitry is to generate, for each applied control value, a first digital code for a direct current (DC) swing and a second digital code for an alternating current (AC) swing at the input node. The calibration circuitry is to determine a final control value of the plurality of control values that minimizes a difference between the first and second digital codes.
