Abstract:
1. A circuit configuration for detecting a maximum in a profile of a measurement signal, the circuit configuration comprising: a first resistor; an operational amplifier having a negative supply potential, an inverting input, a non-inverting input connected to a reference potential being a positive potential, and an output connected through said first resistor to said inverting input; a series circuit having a capacitor and a second resistor, said capacitor directly connected to said second resistor; an input connection for applying the measurement signal too, said input connection connected to said inverting input of said operational amplifier through said series circuit having said capacitor and said second resistor; a third resistor; a first, reverse-biased diode; a second, forward-biased diode; a connection point between said capacitor and said second resistor connected through said third resistor and said first, reverse-biased diode to said negative supply potential of said operational amplifier; and a connection point between said third resistor and said first diode connected to said output of said operational amplifier through said second, forward-biased diode.
