Removal of a common mode voltage in a differential receiver

摘要

A receiver has a plurality of signal lines and a capacitor network having capacitors connected to said signal lines and switches for controlling the connection of said capacitors. The receiver includes a common mode voltage elimination circuit for eliminating a common mode voltage present on said plurality of signal lines by connecting at least one of the capacitor nodes containing the component of said common mode voltage to a node held to a specific voltage value. <IMAGE>
