Claim Text:
1. An integrated circuit, comprising: a differential amplifier having a power supply terminal and an output; an operational amplifier having an input that receives a common mode sensing voltage from the output of the differential amplifier and an output that is connected to the power supply terminal of the differential amplifier; a digital sampler that receives signals from the output of the differential amplifier and that has an output; a digital flip-flop that receives signals from the output of the digital sampler and that has an output; and a summation node circuit that is coupled to the output of the differential amplifier and that has a first input that is coupled to the output of the digital sampler, a second input that is coupled to the output of the digital flip-flop, and an output that is coupled to an input of the digital sampler.
