Abstract
A pulse generator circuit includes: an LC resonant circuit coupled between a first node and a reference node; a first switch coupled between the first node and the reference node; a switching network comprising a second switch coupled between the first node and a respective drive node; and drive circuit having outputs coupled to the first switch and to the second switch of the switching network. The drive circuit is configured to, in repeating cycles: close the first switch so that a current flowing through an inductor of the LC resonant circuit increases during a resonant cycle, when the current flowing through the inductor reaches a threshold value, open the first switch, close the second switch of the switching network for a pulse duration time when the first switch is open, and open the second switch at an expiration of the pulse duration time.
