Abstract:
A microelectromechanical (MEMS) sensor has a capacitance that varies based on a sensed force. A charge signal representing that capacitance is provide at an input node of an amplifier of a sense circuit. The sense circuit includes a filter and analog-to-digital converter. Feedback from the filter and the analog-to-digital converter is also received at the input node of the amplifier. The sense circuit outputs a digital signal that is representative of the sensed force.
