Abstract
An electromagnetic transponder includes an antenna circuit capable of providing signals to a charge pump. The pump includes a first transistor connected to a first capacitor. The transponder also includes means for applying a voltage alternating between first and second values between the gate and the conduction terminal on the side of the first capacitor of the first transistor.
