Abstract

A circuit for reducing power consumption in input ports of an integrated circuit is disclosed. The circuit comprises a plurality of receiver circuits of the integrated circuit for receiving input signals coupled to the integrated circuit; and a bias current generator coupled to the plurality of receiver circuits, the bias current generator providing a bias voltage for each receiver circuit of the plurality of receiver circuits to mirror the current in the bias current generator in each of the receiver circuits. A method of reducing power consumption in input ports of an integrated circuit is also disclosed.
