Abstract
An amplification circuit with a common-mode voltage compensation circuit is shown. The common-mode voltage compensation circuit has a first compensation resistor coupled between an input terminal of a loop filter of the amplification circuit and a control node, and a second compensation resistor coupled between another input terminal of the loop filter and the control node. The control node is coupled to a power ground voltage when the two output signals of the amplification circuit are high, and it is coupled to a power supply voltage when the two output signals of the amplification circuit are low.
