Abstract
A circuit includes a first common mode amplifier including a first input, a second input, and a first output. The first common mode amplifier comprises a first plurality of self-biased differential amplifiers. The circuit also includes a second common mode amplifier including a third input, a fourth input, and a second output, The third input is connected to the second input and the fourth input is connected to the first input. The second common amplifier comprises a second plurality of self-biased differential amplifiers. The circuit further includes a first gain amplifier including a fifth input and a sixth input and a second gain amplifier including a seventh input and an eighth input. The first output is connected to the fifth and eight inputs and the second output is connected to the sixth and seventh inputs.
