Provides a very large gain when opposite signals are applied to
the inputs as compared to the very small gain resulting from
common inputs
An input signal is applied to either input, with the other input connected to
ground
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
Large Ad gain, which is larger than Ac gain.
Common mode gain of ideally zero.
is basically a measure of how much an amplifier “amplifies”
the input signal.
is a logarithmic unit (base 10) of measurement that has no units.
Since the Bel is too large a unit of measure
Also referred to as Large-Signal Amplifiers.
has an efficiency rating between that of Class A and Class B but
poorer signal reproduction than Class A amplifiers.
A certain differential amplifier has a differential voltage gain of 1400 and a common-mode gain of 0.24. Determine the CMMR in decibels.
75.32 dB
Express the 14 current gain in decibel(round it of in to 2 decimal only if necessary)
22.92 dB
Express the 300 voltage gain in decibel(round it of in to 2 decimal only if necessary)
What is the power gain if the current gain is 44 and voltage gain 200?
Determine the output voltage if the input voltage is 14V and the gain is 16
