Abstract
A variable impedance circuit includes at least one fixed resistance and a plurality of transistors between a first and a second terminal. The transistors belonging to the plurality of transistors are arranged parallel to one another and parallel to the resistance and are controllable by a plurality of control signals different from one another and configured in such a way as to obtain a total impedance between said first and second terminals that is substantially variable in a continuous manner.
