Claim:
1. A circuit comprising: an amplifier having an output; a first sample and hold circuit having an input and an output, the input of the first sample and hold circuit coupled to the output of the amplifier; a second sample and hold circuit having an input and an output, the input of the second sample and hold circuit coupled to the output of the amplifier; a differential analog-to-digital converter (ADC) having first and second inputs and an output, the first input of the differential ADC coupled to the output of the first sample and hold circuit, and the second input of the differential ADC coupled to the output of the second sample and hold circuit, the ADC operable to: a control unit operable to control a pulse generation based on the difference between the first voltage offset from the first sample and hold circuit and the second voltage offset from the second sample and hold circuit.
