Abstract
A buffer circuit includes at least one part that is powered by a supply voltage by means of a first initialization transistor, and connected to the ground by means of a second initialization transistor. The circuit is capable of transferring, between an input and an output, an input signal including at least one rising edge and/or one falling edge. The circuit includes a first CMOS inverter, of which the input is connected to the input of the circuit, and of which the output is mounted in series with the input of a second CMOS inverter, with the output of the second CMOS inverter being connected to the output of the circuit. A circuit creates an overvoltage on one of the two inverters during operation.
