Common mode rejection ratio (CMRR) is important performance parameter of any difference amplifier. It is the ratio of the differential gain to the common-mode gain, generally expressed in dB. It signifies the ability of an opamp to reject common mode signal, the signal which appears simultaneously at both its input terminals. The CMRR is of great importance when it comes to noise rejection. For applications involving high CMRR, instrumentation amplifiers consisting of three opamps are generally used. It has a major disadvantage that the value o ....etc

Common Emitter BJT Amplifier Design Current Mirror Design


Some Random Observations
● Conditions for stabilized voltage source biasing
● Emitter resistance, RE, is needed.
● Base voltage source will have finite resistance, RB.
● needs to be much larger than RB.
● Small RB - relative to RS - will attenuate input signal.
● Larger RE permits larger RB, but results in lower gain.
● Gain = -RC/RE for RE >> re.
● Split RE with bypassing increa ....etc

CLASS-D AMPLIFIERS
Abstract
Class D amplifiers present us with a revolutionary solution, which would help us eliminate loss and distortions caused due to conversion of digital signals to analog while amplifying signals before transmitting it to speakers. This inchoate piece of knowledge could prove to detrimental in improving and redefining essence of sound and take it to a different realm.

This type of amplifiers do not require the use of D-A conversion and hence reduce the costs incurred for dev ....etc

A Current-Mirror Differential Amplifier


Prelab
The following prelab questions have been constructed to help you prepare to do the lab
efficiently. Unless otherwise stated, you should assume that like transistors are matched and
that the Early effect is negligible. Please complete these questions before you come to lab.
While you may discuss the prelab questions with your lab partner or with other students in
the class, each student in a lab group should c ....etc

Differential Amplifier Stages - Outline



Linear amplifier layouts:
The practical ways of puttinginputs to,
and taking outputs from,
transistors to form linear amplifiers
There are 12 choices: three
possible nodes to connect to
the input, and for each one,
two nodes from which to take
an output, and two choices of
what to do with the remaining
node (ground it or connect it
to something).
Not all these choices work
well, however. In fact only
three do.
