The system (100) has an amplifier stage (110) including a negative input connected to an output of envelope detector stage (108) and a positive input through which a reference signal (Swref) is received. The stage compares a signal (Vout1) detected at the output with the signal to deliver a control signal (Vcom) to vary gain of the amplifier stage. A comparator stage (112) is connected to the output and the positive input through positive and negative inputs so as to compare the output with the reference signal to deliver a demodulated output signal (Vdout). |
