Abstract
A circuit switches a capacitive value in an exclusive manner to a selected integrated amplifier among a plurality of integrated amplifiers. The circuit includes a first current generator connected between a first supply node and a first node of the circuit, and a second current generator connected between a second supply node and a second node of the circuit. The second current generator is electrically in parallel with the capacitor. An array of switches equal in number to the integrated amplifiers are exclusively switched ON for connecting a directly biased diode between the first node and the second node. Each integrated amplifier has a supply node coupled to a connecting node between a respective diode and a respective connecting switch of the array of switches.
