Abstract:
A receiver frontend having a high-frequency AC-coupled path in parallel to a low-frequency feed-forward path for baseline correction. The low-frequency path blocks the DC common-mode voltage of the input differential signal pair, but passes low-frequency differential signal components (e.g., long strings of a single value, or disparities in the number of 1's and 0's over a long period of time.) The low-frequency path can include a passive network for level shifting and extending the range of acceptable common-mode input voltages. The low-frequency path can also include a differential (e.g., transconductance) amplifier to isolate the common-mode input voltage from the output of the baseline wander correction circuit.

Claim (Index 28):
An integrated circuit, comprising:\n a first terminal for receiving a first signal of a first differential signal pair; a second terminal for receiving a second signal of the first differential signal pair; a DC blocking network coupled between the first differential signal pair and a second differential signal pair, the second differential signal pair coupled to an active receiver stage; and, a baseline correction circuit coupled between the first differential signal pair and the second differential signal pair, the baseline correction circuit to pass differential voltages of the first differential signal pair, the baseline correction circuit including a passive network to adjust the voltage of the first differential signal pair.
