Electronic circuit comprising embedded piezoelectric transformer
First Claim
1. An electronic circuit provided with a piezoelectric transformer for driving an electronic component, in which circuit the transformer comprises a primary plate and a secondary plate made from a piezoelectric material, together with an intermediate insulating layer interposed between the primary and secondary plates, the primary plate being arranged to transmit a displacement signal to the secondary plate through the intermediate layer in response to a primary signal that is transmitted to the primary plate via the electronic circuit, and the secondary plate delivering a secondary signal to the electronic component as a function of the primary signal for the purpose of driving the electronic component to which the secondary plate is connected, the circuit being characterized by the fact that it comprises a first layer in which the primary plate is integrated and a second layer in which the secondary plate is integrated, the first and second layers being galvanically isolated from each other by the intermediate layer.
