Abstract
A method is for processing an incident signal, in which the incident signal is delivered to a transconductor stage, and a current output of the transconductor stage is coupled to an output capacitor so as to deliver to the output capacitor a current signal lasting for at least part of the first half-period of each period of a periodic signal and to thus obtain a frequency-transposed signal at the output capacitor. Upon the occurrence of each part of the first half-period, the voltage of the current output, seen from the output capacitor, is reset to a value equal to that of the voltage of the output capacitor.
