Abstract
Circuitry includes an acquiring circuit to acquire period and phase information of an oscillation. The acquiring circuit includes a first input electrically coupled to a first connection and a second input electrically coupled to a second connection. The first connection and the second connection are for electrically coupling to an oscillating circuit. A control circuit includes a first input electrically coupled to an output of the acquiring circuit. The control circuit includes a second input electrically coupled to a third connection for supply of a voltage that is based on the rectified voltage. A switch includes a controlled segment for electrically coupling a fourth connection to a reference potential connection, and a control connection that is electrically coupled to an output of the control circuit to excite an oscillation in the oscillating circuit via a DC voltage.
