The present disclosure teaches a receiving circuit for use with a vehicle and serving for receiving a signal of a transponder. The receiving circuit may include a plurality of input paths each having an antenna and a multiplexer with a plurality of switches controlled by control signals and connecting at least one of the input paths to at least one further device in the form of a discharger and/or detuner and/or amplifier.

Receiving circuit for a vehicle remote

The invention relates to a driver circuit and an active transmitter device, a series circuit consisting of a first capacitor () and a second capacitor () being charged to a reference voltage by way of a charging current and the charged capacitors being discharged via the inductor () by an oscillating discharge, the discharge being terminated when the current through the inductor has completed an entire oscillation period or a multiple thereof.

Driver circuit for an inductor and active transmitter device having a driver circuit

A driver circuit, a method for operating an inductor coil and an active transmission system, wherein a capacitor is charged by means of a charging current to a reference voltage and the charged capacitor is discharged in an oscillating manner via the inductor coil. The inductor coil is short-circuited when the voltage on the capacitor or a current flowing in the inductor coil has passed through at least one complete oscillating period.

Driver circuit for an inductor coil

The present disclosure relates to an antenna driver circuit for an antenna associated with a motor vehicle. The antenna driver circuit may include at least one pair of output paths to at least one antenna for forming at least one oscillatory circuit composed of in each case an antenna and at least one capacitor, and a plurality of switches in the form of MOSFETs controlled by control signals in one respective oscillatory circuit with an antenna. In the respective oscillatory circuit, at least two controllable switches may be arranged in an anti-serial fashion with respect to one another in that their drain connections are connected together, and/or source connections of controllable switches are connected to one another via an antenna.
