Vin 0-20 mV, Vout 0-3 V
The set of data points, Vout = 0 V @ Vin = -20 mV, Vout = 3 V @ Vin = +20 mV, see the transfer curve below.
0 = m(-0.02) + b
3 = m(0.02) + b
After algebraic manipulation, yield the solution, m = 75 and b = 1.5, rewrite m and b to new equation.
Vout = 75Vin + 1.5
The equation above similar to the CASE1: Vout = +mVin + b circuit.
We can calculate the value of R1, R2, RF and RG by the following equations:
The circuit configuration which yields a solution is shown below.
