<p>A method for demodulating an RF input signal using an envelope detector and synchronous switching of the input signal before entering and after leaving the envelope detector, the envelope detector having a non-linear transfer function acting essentially as a squaring function. The invention also relates to an electronic receiver circuit performing such a method, and to an RF receiver comprising such an electronic receiver, and to an electronic device comprising such an RF receiver, and to the use of such an RF receiver as a wake-up receiver.</p> |
