Abstract
According to one aspect of the invention, an apparatus is provided which includes a first amplifier and a common mode feedback circuit. The first amplifier includes a first input, a second input, a first output, and a second output. The first input and the second input are coupled to receive a first input voltage and a second input voltage, respectively. The first and second outputs provide a first output voltage and a second output voltage, respectively. The common mode feedback circuit has first and second switched capacitors coupled to provide a common mode feedback signal based on the first and second output voltages to the first and second inputs of first amplifier.
