A receiver circuit, in accordance with the present invention, includes a first stage having an input for receiving input signals and an output node. The first stage includes an amplifier, and a second stage includes an input coupled to the output of the first stage. The second stage also includes a logic gate coupled to the output of the first stage, the logic gate having an output representing the output of the receiver circuit, and a feed back element coupled from the logic gate output and connecting to a switching element. The switching element, being responsive to the logic gate output, switches a current source on and off to adjust a switchpoint of the receiver circuit.
