Abstract
A discrete-time high voltage generating circuitry is described, configured to provide a discrete-time high voltage at a high voltage output only during defined high voltage periods. The discrete-time high voltage generating circuitry includes a current mirror circuitry configured to receive a supply current from a high voltage source and to provide a slew current. The discrete-time high voltage generating circuitry is configured to generate the discrete-time high voltage using the slew current. Further, a method to operate a discrete-time high voltage generating circuitry is described. The circuitry and method may be used to provide a discrete-time self-test bias voltage to at least one capacitive load such as a capacitive MEMS element.
