Abstract
A circuit for generating a D.C. signal for controlling an A.C. switch referenced to a first potential, from a high-frequency signal referenced to a second potential, including: a first capacitive element connecting a first input terminal, intended to receive the high-frequency signal, to the cathode of a rectifying element having its anode connected to a first output terminal intended to be connected to a control terminal of the switch; and a second capacitive element connecting a second input terminal, intended to be connected to the second reference potential, to a second output terminal intended to be connected to the first reference potential, a second rectifying element connecting the cathode of the first rectifying element to the second output terminal.
