Abstract
In one embodiment, a method for detecting functional state of a microelectromechanical (MEMS) sensor is described. The method includes monitoring an input common-mode feedback (ICMFB) voltage generated by an ICMFB circuit coupled to the MEMS sensor through a plurality of nodes. The method also includes determining, using the monitored ICMFB voltage, whether all of the plurality of nodes of the MEMS sensor are electrically connected to the ICMFB circuit.
