OP AMP MCQ Level – 1 - Physics MCQ

Since diode does not conduct in reverse bias hence, the circuit given in option (c) does not operate for a negative feedback.
The correct answer is:

Integrator circuit is as shown below

The correct answer is: capacitor

The attenuation B, of the feedback circuit is

= [1 + 200000(0.0435)](2MΩ)
= 17.4GΩ

= 8.6Ω
The correct answer is: 17.4GΩ; 8.6/mΩ

It is called the unity-gain frequency
The correct answer is: The unity-gain frequency

R₁ maintains the high input impedance.
The correct answer is: Maintain high input impedance

As the voltage gain is infinite, the voltage between the inverting and non-inverting terminal (i.e. differential input voltage) is essentially zero for finite output voltage.

Since the input resistors are equal; 
R= 100/kΩ
The output voltage is

Whereas, the input average

Shows that average of the input value is the same magnitude as V_out but of opposite sign.
The correct answer is: The average of the input values is the same magnitude as V_out but of opposite sign

It extends from 0Hz to the upper critical frequency.
The correct answer is: extends from 0Hz to the upper critical frequency

= -4V
The correct answer is: a ramp function of -4V

A buffer amplifier (sometimes simply called a buffer) is one that provides electrical impedance transformation from one circuit to another, with the aim of the signal source being unaffected by (“buffered from”) whatever currents that the load may produce.
The correct answer is: buffer amplifier
