Question:
(a) The circuit of FIGURE is known as a transimpedance circuit used for the measurement of very small currents. Derive the relationship between the output voltage V and the input current I; i.e. if V = KI find k in terms of R1, R2 and Rf.
(b) Calculate the current I if Rf = 10 MΩ, R1 = 90 MΩ. R2 = 10 kΩ and V -0.1 V.
(c) Model the circuit of FIGURE using PSPICE (using an ideal op-amp] and use the model to confirm the calculation made in (b).

This is an assignment of circuit theory. This is telling about transimpedance circuit. This circuit is mainly used for measuring very low resistance. Here the value of feedback resistance is given and also divider resistance values are also mentioned. According to that given values, it is required to measure input current which passes through the feedback resistance and generate the required output voltage. Initially, it is required to calculate the current, voltage and resistance relationship. Then from that relation calculate input current according to the required output voltage. Here PSPICE PROGRAMME, SCHEMATIC & SIMULATION done. Also simulation files are given as an attachment.
Could you send the first two files from the zip folder in pdf format please, as I cannot open them- .cir (file) and (.sch). SCHEMATIC TO PDF DONE AND ALSO GO THROUGH THE .RAR FILE. ALL SNAP SHOT OF PROGRAM FILE AND SCHEMATIC FILE Thank you very much I am getting best time thank you very much for the help. All for my assignment you done great job I will be back with other one.
Please provide answer to (c) only (PSPICE format). Please attach a file with the circuit in 'PSPICE', showing the measured value of I as per Question (b) Derive the relationship between the output voltage V and the input current I; i.e. if V = KI find k in terms of R1, R2 and Rf.
An input signal ranges in amplitude from +1 V to -1 V, which matches the dynamic range of the ADC being used. No clipping of the input signal occurs.
