Abstract
A system and method for converting an analog signal to a digital signal is provided including a first circuit () having a signal range and an input for receiving a first signal, and a second circuit () having an input receiving the analog signal and a first output coupled to the input of the first circuit. The first circuit () includes an amplifier (). The first circuit () samples the first signal and produces the digital signal from the first signal using the amplifier. A second output of the second circuit () is coupled to the amplifier (). The second circuit () samples and scales the analog signal via the amplifier () to produce the first signal within the signal range and cancels an offset of the first signal. The system and method reduce power consumption and save device area.
