Abstract
A circuit is provided having a differential difference amplifier (DDA) having first and second inputs to receive a desired body bias signal, and a third input to receive a supply voltage, the DDA configured to generate an intermediate output signal, the intermediate output signal coupled to an output buffer generating an output signal having a desired gain, the DDA having a fourth input, to cause the output signal to reference to variations in the supply voltage.
