Npf radiofrequency device

Abstract

An NPF radiofrequency device includes a first end terminal E, four first branches BR, BR, BR, BRconnected to Eand each including a capacitor, respectively C, C, C, C, having the same capacitance, including a first terminal and a second terminal connected to ground, and a switch arranged between Eand the first terminal of the capacitor of the first branch; the device being designed to, in each first branch BR, close the switch at each time pT+(i)T/4, for T/4, where p is a natural number and Tis the period of the clock signal; the device including at least two successive second branches from among an ordered set of second branches BR, BR, BR, BR, the second branch BRincluding a second end terminal E, and each second branch BRof the device including, for each first branch, BR, i=0 to 3, a switch between the first terminal of the capacitor Cand the second branch, the device being designed to close the switch at each pT+(i+k)T/4, for T/4.
