Abstract
A data receiver, a method of operating a data receiver, and an integrated coupling system in a data receiver are disclosed. In one embodiment, the data receiver comprises an input terminal for receiving an input data signal, an input amplifier for amplifying selected components of the input data signal, and an input signal path for transmitting specified high-frequency components and a baseline component of the input data signal from the input terminal to the input amplifier. The data receiver further comprises a feed-forward resistive network connected to the input terminal and to the input amplifier. This feed forward resistive network is used to forward a low-frequency drift compensation signal from the input terminal to the input amplifier, using a passive resistive network, to compensate for low frequency variations in the input data signal, and to develop a desired bias voltage at the input amplifier.
