Obtain the output voltage equation of integrator and differentiator of Op-Amp?
Answers
Answer:
Differential Amplifier Equation
If all the resistors are all of the same ohmic value, that is: R1 = R2 = R3 = R4 then the circuit will become a Unity Gain Differential Amplifier and the voltage gain of the amplifier will be exactly one or unity. Then the output expression would simply be Vout = V2 – V1.
Explanation:
Answer:
Operational amplifiers can be used as part of a positive or negative feedback amplifier or as an adder or subtractor type circuit using just pure resistances in both the input and the feedback loop.
Operational amplifiers can be used as part of a positive or negative feedback amplifier or as an adder or subtractor type circuit using just pure resistances in both the input and the feedback loop.But what if we where to change the purely resistive ( Rƒ ) feedback element of an inverting amplifier with a frequency dependant complex element that has a reactance, ( X ), such as a Capacitor, C. What would be the effect on the op-amps voltage gain transfer function over its frequency range as a result of this complex impedance.
