<p>A circuit for switching a capacitor (C) in an exclusive manner, on the selected one of a plurality of integrated amplifiers (A1, A2, ... AN) comprises a first current generator (IB) connected between a first supply node (VCC) and a first node of the circuit (H), a second current generator (IC) connected between a second supply node (GND) and a second node (L) of the circuit, electrically in parallel to the capacitor (C), an array of switches (S1, S2, ..., SN) of the same number of the integrated amplifiers, exclusively switcheable on, each connecting a directly biased diode (D1, D2, ..., DN) between the first node (H) and the second node (L), each integrated amplifier having a supply node coupled to the connecting node between a respective diode and a respective connecting switch of said array. <IMAGE></p> |
