ABSTRACT:
An electronic device, for example a signal receiver mounted on a vehicle for opening and closing the doors of the vehicle in response to telecontrol signals from a remote source, includes an intermediate frequency amplifier. The intermediate frequency amplifier comprises two amplifier stages arranged in cascade with respect to the input signal, with the biasing terminals of the two stages being connected in series across the supply. The arrangement gives much reduced current consumption.
