Patent ID: 7362010

Claim:
A receiver circuit for a vehicle, comprising: a current-sensing switching circuit including: a first terminal clamp for a current supply of a first unit based on a state of a second unit; a second terminal clamp configured to detect the state of the second unit; wherein the first terminal clamp is configured to be switched on the basis of a current picked off at the second terminal clamp, the first unit including an amplifier, the second unit including a high-frequency receiver; a switching circuit configured to switch the first terminal clamp; a current-mirror system including potential-dividing resistors configured to generate a voltage proportional to the current at the second terminal clamp to control the switching circuit; a first transistor including a short-circuited base and collector; a first load resistor that provides a first branching of the mirror system; and a second transistor and a second load resistor that provides a second branching of the mirror system; wherein voltage-dividing resistors are connected between emitters of the transistors and are connected to the current supply between the voltage-dividing resistors, the switching circuit being connected to the collector of the second transistor, and the second terminal clamp being arranged as an emitter of the first transistor.
