Abstract
An AC coupling circuit is disclosed herein. An embodiment of the circuit comprises a first differential input and a second differential input. A first resistor is connected between the first differential input and the second differential input. A first capacitor is connected between the first differential input and a first differential output. A second capacitor is connected between the second differential input and a second differential output. A second resistor is connected between the first differential output and a node. A third resistor is connected between the second differential output and the node. A first potential is applied to the node.
