Explanation Given: Input resistance = 20k Ω Gain = 10 Calculation: The given figure is The input resistance of the differential op-amp can be calculated as R i d = 2 R 1 20 kΩ = 2 R 1 R 1 = 20 kΩ 2 R 1 = 10 kΩ The value of common-mode gain for a differential amplifier is 0. That is, 1 − R 2 R 3 R 1 R 4 = 0 R 2 R 1 = R 4 R 3

Operational Amplifier

An operational amplifier also called op amp is an integrated circuit or analog circuit that takes input as a differential voltage and produces output as a single-ended voltage. It is an IC that can amplify weak electric signals.An op amp has one output p…

In the inverting intellectual operational amplifier circuit, R1 = 40k, R2 = 100K, R3 = 10k, R4 = 20k and R5 = 5k. Find the value of the output voltage v0 when the voltages are applied to the inputs of the circuit.

Find the value of resistance so the circuit behave as a difference amplifier with input resistance 20 kilo ohm and a gain of 10.

Do you observe any relation between the output at one time constant (T) and the value of gain (k). Why the output for 3 times constant (3T) is not the same for different cases.
