Abstract: A programmable receiver implemented in an integrated circuit device is described. The programmable receiver comprises a pre-amplifier circuit coupled to receive an input signal, the pre-amplifier circuit having a programmable current source; and an amplifier circuit coupled to receive an output of the pre-amplifier circuit; wherein the programmable current source is coupled to receive a control signal to enable the receiver to be switched between a high performance mode and a low performance mode. A method of implementing a programmable receiver in an integrated circuit is also described.
