Abstract
A circuit arrangement detects a maximum in a profile of a measurement signal. The circuit arrangement has an operational amplifier with a non-inverting input connected to a reference potential and an output connected to an inverting input via a first resistor. The first resistor has an input connection, to which the measurement signal is applied and which is connected to the inverting input of the operational amplifier via a series circuit containing a capacitor and a second resistor. The connection point between the capacitor and the second resistor is connected to the negative supply potential of the operational amplifier via a third resistor and a first, reverse-biased diode. The connection point between the third resistor and the first diode is connected to the output of the operational amplifier via a second, forward-biased diode. The reference potential is a positive potential.
