Abstract
A feedback signal is employed to facilitate enhancing an acoustic overload point and electrostatic discharge protection of a sensor component and associated circuit. The sensor component comprises a backplate component and a diaphragm component. The backplate component is biased to a low-level voltage associated with a ground. The diaphragm component is biased to a defined high-voltage associated with a charge pump. The diaphragm component generates a signal based on movement of the diaphragm component in relation to the backplate component in response to the input signal. A feedback component receives the signal from the diaphragm component and generates an inverted signal based on the signal. The inverted signal or a processed inverted signal, which can be derived from a filter component that filters the inverted signal, is transmitted to the backplate component.
