Abstract: A circuit with a successive approximation analog-to-digital converter utilizes a feedback path and is operated for example in accordance with the successive approximation method. The feedback path is configured to translate a digital signal in accordance with a prescribed function and to furthermore convert the translated digital signal into an analog feedback signal. For example, the prescribed function can be an exponential function. As such, it can be possible to convert an input signal into an output signal by means of a nonlinear characteristic.
