Abstract:
A bias circuit for a capacitive sensor may include a variable impedance element coupled to a capacitor of the capacitive sensor wherein an impedance of the variable impedance element is varied in accordance with a temperature associated with the bias circuit and an active feedback circuit coupled between the variable impedance element and an output of a processing circuit for processing a signal generated by the capacitive sensor and configured to drive the variable impedance element to force a direct-current (DC) voltage level of an output of the capacitive sensor to a desired voltage.

Claim (Index 3):
The bias circuit of  claim 1 , wherein the capacitive sensor comprises a microelectromechanical systems microphone.
