Abstract
A resonant element driver circuit includes a NMOS transistor and a PMOS transistor that are configured to drive a resonant element. The resonant element driver circuit includes biasing circuitry that is configured to bias the PMOS transistor. The biasing circuitry receives a reference signal that is used to set the biasing on the PMOS transistor. The resonant element driver further includes mirror circuitry that tracks current flowing through the NMOS and PMOS transistors.
