This is the Current / voltage conversion circuit with fast output voltage rising time, perfect frequency characteristics as the inverting amplifier, high-speed FET input operational amplifier. For making the output be consistent with the polarity of the input signal, Al output end is connected inverting amplifier A2. If you ignore the effects of stray capacitance, the output voltage rising time is about 3OμS, and it will switch the 50nA input current into lV output voltage. In the circuit, R2 is used to prevent the input oscillation; VTl and VT2 are connected as diodes, which is used for input protection of Al.
