1. The problem statement, all variables and given/known data (a) 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 kΩ, R2 = 10 kΩ and V –0.1 V. (c) Model the circuit using PSPICE [using an ideal opamp] and use the model to confirm the calculation made in (b). 2. Relevant equations 3. The attempt at a solution (a) V= KI, K= R2/ R2+ (Rf*R1/Rf+R1) (b) I= V/K , I= -0.1/(10k/10k+(90k*10M/90k+10M), I= -0.992A (too big a current?) (c) Im not sure how to complete this schematic, I need to check current calculation in (b). I dont kow what "Vin" is. Any help is greatly appreciated as I have no training on this software.
