    Abstract: A programmable equalizer and related method are provided. The equalizer includes a pair of current-setting field effect transistors (FETs) coupled in series with a pair of input FETs and a pair of load resistors, respectively, between a first voltage rail (Vdd) and a second voltage rail (ground). A programmable equalization circuit is coupled between the sources of the input FETs, comprising a plurality of selectable resistive paths and a variable capacitor, which could also be configured as a plurality of selectable capacitive paths. Each of the selectable resistive paths (as well as each of the selectable capacitive paths) include a selection FET for selectively coupling the corresponding resistive (or capacitive) path between the sources of the input FETs. In the case where one of the input FETs is biased with a reference gate voltage, the source of each selection FET is coupled to the source of such input FET.

    Abstract: Methods, systems, and circuits for providing reception and capture of data using a mismatched impedance and an equalizer to save power are disclosed. A data receiver in communication with a transmission line, the data receiver having a termination impedance that is mismatched with respect to a characteristic impedance of the transmission line; and an equalizer in communication with the data receiver, the equalizer configured to receive a channel-transmitted data signal from the data receiver and to re-shape the signal to reduce distortion RC attenuation; wherein the circuit is configured to selectably operate in a first mode wherein the termination impedance is matched with respect to the characteristic impedance of the transmission line and a second mode wherein the termination impedance is mismatched with respect to the characteristic impedance of the transmission line and the signal is not recoverable but-for the equalizer.
