FMSS_Prelim Quiz 1

Provides a very large gain when opposite signals are applied to

the inputs as compared to the very small gain resulting from

common inputs

• Operational amplifier
• Inverting amplifier
• Non-inverting amplifier
• Differential amplifier

An input signal is applied to either input, with the other input connected to

ground

• Single-ended amplifier configuration
• Inverting amplifier with both inputs grounded
• Non-inverting amplifier with one input floating
• Differential amplifier configuration with one input grounded.

If two opposite polarity input signals are applied

• Single Ended

• Common Mode

• Double Ended

• Operational Amplifiers

Using constant __________circuit to reduce the

common-mode gain.

• Voltage

• Resistor

• Current Source

• DC Bias

The higher the CMMR the better

• True

• False

What are the important Characteristic of Differential

Amplifier

• High output impedance, low common-mode rejection ratio, and inability to differentiate signals.
• Large Ad gain, which is larger than Ac gain.

  Common mode gain of ideally zero.

• Low input impedance, high gain for common-mode signals, and poor noise rejection.
• Low input impedance, high output impedance, low CMRR, and inability to amplify signals.

is basically a measure of how much an amplifier “amplifies”

the input signal.

• Gain
• Distortion
• Frequency
• Volume

is a logarithmic unit (base 10) of measurement that has no units.

Since the Bel is too large a unit of measure

• Watt
• Decibel
• Hertz
• Bel

Also referred to as Large-Signal Amplifiers.

• Voltage Amplifiers
• Current Amplifiers
• Signal Boosters
• Power Amplifiers

has an efficiency rating between that of Class A and Class B but

poorer signal reproduction than Class A amplifiers.

• Class C
• Class D
• Class A/B
• Class AB
