Specify the voltage gain of non-inverting amplifier with feedback amplifier with and without feedback?
A. A= Vo/Vid, AF = Vf/Vo
B. A= Vf/Vid, AF= Vo/Vf
C. A= Vo/Vid, AF= Voin
D. A= Vf/Vid, AF = Vf/Vin
Answer:A
Specify the voltage gain of non-inverting amplifier with feedback amplifier with and without feedback?
A. A= Vo/Vid, AF = Vf/Vo B. A= Vf/Vid, AF= Vo/Vf C. A= Vo/Vid, AF= Voin D. A= Vf/Vid, AF = Vf/Vin
Explanation: The voltage gain of op-amp with feedback is the open loop voltage gain, A=Vo /Vid. The voltage gain of op-amp without feedback is the closed loop voltage gain, AF = Vo /Vin.
