Question

Given the following parameters Vin = 14 V, R1 = 24 kΩ, R2 = 12 kΩ, R3 = 6 kΩ,

R4 = 3 kΩ and a feedback resistor of 10 kΩ. Calculate the output voltage V0. (9)

Answer 1

$V_o= (-\frac{R_f}{R})V_1\\$

In the first stage

$V_o= (-\frac{10*10^3}{24*10^3})*14\\ =-\frac{17.5}{3}= -5.833333V$

In the second stage

$V_o= (-\frac{10*10^3}{12*10^3})*14\\ =-\frac{35}{3}= -11.66666 V$

In the third stage

$V_o= (-\frac{10*10^3}{6*10^3})*14\\ =-\frac{70}{3}=-23.33333 V$

In the fourth stage

$V_o= (-\frac{10*10^3}{3*10^3})*14\\ =-\frac{140}{3}=-46.66666 V$
