摘要
An apparatus for performing baseline wander correction (BLWC) with the aid of differential wander current sensing includes filters and a correction circuit. The filters are positioned in a front-end circuit of a receiver and coupled to a set of input terminals of the receiver, and filter a set of input signals on the set of input terminals to generate a set of differential signals on a set of secondary terminals, for further usage by the receiver. The correction circuit is positioned in the frontend circuit and electrically connected to the set of input terminals and the set of secondary terminals, and performs BLWC on the set of differential signals according to the set of input signals. In the correction circuit, amplifiers and resistors form a differential wander current sensor to sense differential wander current, and a set of current mirrors generate corresponding baseline wander compensation current to perform BLWC.
