Abstract
A sensor interface circuit is provided for resolving sensor signals from a plurality of sensors into a digital sensor signal. The sensor interface circuit includes a relaxation oscillator that receives and pre-processes the sensor signals to generate an analog sensor signal. The relaxation oscillator includes one or more dynamic circuits. The sensor interface circuit also includes a monitoring module for receiving the analog sensor signal and generating the digital sensor signal in response thereto. There is also provided a sensor system front-end and a relaxation oscillator.
