Semiconductor Body, Circuit Arrangement Having the Semiconductor Body and Method

摘要

An input circuit arrangement (1) comprises an input (2), a comparator (30), and an evaluation circuit (50). The input (2) is designed for coupling to a first terminal (101) of an impedance (100) and for feeding an input signal (ES). The comparator (30) is connected to the input (2) of the input circuit arrangement (1) and is designed for delivering an activation signal (S1) to an output (31) as a function of a comparison of the input signal (ES) with an adjustable threshold (SW1). Furthermore, the evaluation circuit (50) is connected to the input (2) of the input circuit arrangement (1) and for its activation to the output (31) of the comparator (30) and is designed for evaluating the value of the impedance (100) that can be connected.
