ABSTRACT:
A transimpedance amplifier circuit includes an inverting voltage amplifier having an input being supplied with an input current and an output carrying an output voltage. A coupling member is connected between the input and the output of the voltage amplifier. The coupling member has two diodes being connected antiserially to one another between the input and the output of the voltage amplifier with a common node point. A transistor has a load path being connected between the common node point and a ground potential. A differential amplifier has one input connected to the input of the voltage amplifier, another input connected to the output of the voltage amplifier, and an output. A low-pass filter is connected downstream of the differential amplifier for furnishing a trigger signal at the output to the transistor.
