Abstract

An integrated circuit comprises a pin coupled to receive signals from outside the integrated circuit and an input network. The input network equalizes incoming signals by attenuating lower frequency input signals more than higher frequency input signals received at the pin. The input network is configured to generate a DC bias voltage at an output of the input network in response to an AC coupled input signal or a DC coupled input signal received at the pin with a wide common-mode range.
