Abstract
A circuit for implementing a differential input receiver is described. The circuit comprises an input circuit having a first input node and a second input node configured to receive a differential input signal; a first output circuit having a first capacitor coupled between the first input node and a first output node and a second capacitor coupled between the second input node and a second output node, wherein the first output circuit generates an output signal at the first output and the second output when the input signal is in a first frequency range; and a second output circuit comprising an amplifier having a first amplifier input coupled to the first input node and a second amplifier input coupled to the second input node, wherein the second output circuit generates an output signal when the input signal is in a second frequency range which extends lower than the first frequency range. A method of implementing a differential input receiver is also described. The circuits and methods also allow for offset compensation.
