Question

Q1)The Miller effect can be described as....

A)

An effect by which a capacitor connected at the input of a high-gain amplifier appears reflected at the output of the amplifier divided by the gain.

B)

An effect by which a capacitor connected at the output of a high-gain amplifier appears reflected at the input of the amplifier multiplied by the gain.

C)

An effect by which a capacitor connected in the feedback path of a high-gain amplifier appears reflected at the input of the amplifier multiplied by the gain.

D) An effect by which a capacitor connected in the feedback path of a high-gain amplifier appears reflected at the output of the amplifier multiplied by the gain

Q2)A transistor amplifier is designed with a nominal gain of 40 dB. A sinusoidal signal of amplitude 15mV is applied at the input, and a sinusoidal signal of amplitude 1V is measured at the output. Which of the following could be the cause for the amplifier to exhibit this behavior?

A)		Loading effects at the input and/or output of the amplifier
B)		The frequency of the input signal is outside the midband range of the amplifier
C)		Any of the above items could cause this behavior
D)		None of the above items could cause this behavior
