ABSTRACT:
An oscillator circuit produces first and second oscillating logic signals that are of a same frequency and are non-overlapping in a first logic state. This oscillator includes a flip-flop circuit to produce third and fourth oscillating logic signals of opposite polarities, this flip-flop circuit being driven by first and second driving logic signals. First and second logic gates receive the third and fourth logic signals and produce the first and second logic signals, the logic state transitions in the first and second logic signals being produced as a function of the logic state transitions of the third and fourth logic signals. The first and second logic gates are organized so as to introduce a delay into the transitions from a second logic state to the first logic state, in the first and second logic signals, with respect to transitions in the third and fourth logic signals. First and second RC type circuits produce the first and second driving signals to control the transitions in the third and fourth logic signals. The oscillator circuit can be used in a switch-over control circuit for a load pump type of high-voltage generator.
