  • Patent number: 12460947
    Abstract: An electronic module for an inductive sensor apparatus is provided which comprises at least one voltage-controlled current source, a current source port connected to the at least one voltage-controlled current source for providing a voltage-controlled current from the at least one voltage-controlled current source, an adder device, an adder input port connected to the adder device, and an adder output port which is connected to the adder device. The current source port is connectable to an electrical resonant circuit and/or to a coil element. The adder input port is connectable to the current source port or to at least one further coil element. By way of the adder device, an operation of addition and/or subtraction of a voltage applied to the adder input port and at least one offset voltage is performed. An evaluation signal for evaluation by an evaluation device is providable at the adder output port.
