Abstract
A circuit for biasing a transducer including a first plate and a second plate includes a front-end buffer and a charge pump. The front-end buffer generates an internal signal at an internal node in response to a voltage signal of the second plate. The transducer receives the incident sound wave at the first plate to generate the voltage signal at the second plate. The charge pump boosts the internal signal into a boost voltage at the first plate according to a first clock signal.
