发明名称 On-Chip AC Coupled Receiver with Real-Time Linear Baseline-Wander Compensation
摘要 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.

主权项 1. An on-chip AC coupled receiver with baseline wander compensation, the receiver comprising: a first input terminal to receive a first input signal; first AC coupling circuitry between the first input terminal and a first node, the first AC coupling circuitry coupling the first input signal into a first coupled signal at the first node; a data recovery stage to recover data from the first coupled signal at the first node; and a control loop to sense low frequency signal content at the first node and to use a linear buffer in adjusting the first coupled signal at the first node based on the low frequency signal content.
