Physics Quiz: UNIT II AMPLIFIERS

What is the main purpose of a CS amplifier?

• To convert the input signal into digital format

• To decrease the voltage of the input signal

• To filter out the input signal

• To amplify the voltage of the input signal

What is the gain of a CG amplifier?

• 3

• 2

• 1

• 4

Explain the frequency response of a source follower.

• Characterized by a high input impedance and a low output impedance

• Characterized by a high input impedance and a high output impedance

• Characterized by a low input impedance and a low output impedance

• Characterized by a low input impedance and a high output impedance

How is the gain of a CS amplifier calculated?

• Av = gm + Rd

• Av = gm * Rd

• Av = -gm / Rd

• Av = -gm * Rd

What is the frequency response of a CG amplifier?

• Remains constant at all frequencies

• Increases with frequency

• Decreases with frequency

• Relatively flat
