Question

Part 1: Gain =8, R1=5k, R2=20k, R5=100, and V1=1V. Find Vout/Vin.

Part 2: Let R4=0 and R3=∞. Find Vout/Vin. (Hint: make sure the button called Enable Biased Voltage

Display is depressed) (Another Hint: when a resistance is zero, short it; when a resistance is

infinity, delete it).

Part 3: Let R4=2k and R3=∞. Find Vout/Vin.

Part 4: Let R4=0 and R3=1000. Find Vout/Vin.

Part 5:Let R4=2k and R3=1000. Find Vout/Vin.

Answer 1

Part 1: Gain=8 circuit

Part 2:

Vout/Vin = 0/1 = 0

Part 3:

Vout/Vin = 3.03/1 = 3.03

Part 4:

Vout/Vin = 0/1 = 0

Part 5:

Vout/Vin = 3.03/1 = 3.03
