  • Wide dynamic range transimpedance amplifier circuit
    Patent number: 6028482
    Abstract: A transimpedance amplifier circuit includes an inverting amplifier having an input being supplied with an input current, an output carrying an output voltage and a transconductance being adjusted as a function of the input current. A coupling member is connected between the input and the output of the inverting amplifier and has a controllable impedance. A differential amplifier has one input connected to the input and another input connected to the output of the inverting amplifier. A low-pass filter is connected downstream of the differential amplifier and has an output supplying a trigger signal for the coupling member.
