Abstract: An apparatus for reading out a modulated time-continuous sensor output signal includes a loop filter, a sample-quantizer and a feedback circuit. The loop filter filters the sensor output signal to provide a filtered sensor output signal, and amplifies frequency proportions present in a frequency range. The sample-quantizer samples and quantizes the filtered sensor output signal to provide a time-discrete, quantized sensor output signal. The feedback circuit feeds a feedback signal based on the time-discrete, quantized sensor output signal back to the loop filter and provides a readout signal.

Abstract: A sensor readout includes a selector circuit, a predictor circuit, and a select controller. The selector circuit receives a plurality of actual sensor inputs. Each actual sensor input is provided to the selector circuit along a corresponding channel. The selector circuit also passes a selected sensor input. The predictor circuit receives the selected sensor input into a signal history and generates predicted sensor inputs. The select controller receives the predicted sensor inputs, determines which of the predicted sensor inputs is most changed from the actual sensor inputs as the most changed input, and directs the selector circuit to pass a next signal on a the channel having the most changed input.
