What do you call the ratio of the unity-gain frequency to the cutoff frequency?
Open loop gain
CMRR
Common Mode Gain
Closed Loop Gain
When the input signals are both the same, a common signal due to the inputs can be defined as the average of the sum of the signals.
True
False
Cannot be determined
Ideally, the value of the CMRR is larger. However, for better circuit operation, the practical value of the CMRR is infinite.
True
False
Mostly false
Mostly true
The output offset voltage is both the input offset voltage and the closed loop gain.
True
False
Mostly true
Mostly false
Inverting amplifier is widely used because it has a unit gain.
True
False
Mostly true
Mostly false
If the frequency is increased, the input impedance will be decreased.
True
False
Mostly true
Mostly false
If the frequency is increased, the output impedance will be increased also.
True
False
Mostly true
Mostly false
If input supply is increased, the gain will be decreased.
True

Mostly false
The power consumption of a circuit increases if the supply voltage is increased.
True
