An on-chip AC coupled receiver with baseline wander compensation. The receiver may be used for either single ended or differential signals. The receiver includes an input terminal to receive an input signal. AC coupling circuitry is between the input terminal and a node and couples the input signal into a coupled signal at the node. A control loop senses low frequency signal content at the node and uses a linear buffer in adjusting the coupled signal at the node based on the low frequency signal content. The operation of the control loop compensates for potential baseline wander in the coupled signal. An input stage to recovers data from the coupled signal at the node.
