Abstract
A method of tuning an input signal (S) is described. The method comprises the steps of amplifying the input signal (S) by a gain element () having a variable impedance () associated therewith and thereby generating an output signal (C), comparing the output signal (C) with a reference voltage (V), tuning the variable impedance () such that the impedance is increased if the amplitude of the output signal (C) is smaller than the reference voltage (V), and that the impedance is decreased if the amplitude of the output signal (C) is greater than the reference voltage (V).
