Abstract
The disclosure relates to a transducer assembly like a microphone including a bias circuit having a charge pump and a filter circuit coupled to a transducer. The filter circuit includes a voltage-controlled resistor located between an output of the charge pump and the transducer, and a capacitor coupled to the voltage-controlled resistor opposite the charge pump, wherein the bias circuit is configured with a larger bandwidth for faster settling during transient operation than during steady-state operation.
