Abstract

The passive transponder comprises an antenna () connected to an integrated circuit () the analogue part of which includes a passive voltage rectifier () supplying a rectified voltage (V) and an active multiplier or booster () for said rectified voltage which is formed by a capacitor (C) switched to a relatively low frequency, for example 1 MHz, by means of switches formed by transistors (to) controlled using an oscillator ().
