Introduction to Differential Amplifier

• A device which accepts an input signal and produces an output signal proportional to the input, is called an amplifier.

Introduction to Differential Amplifier

• A device which accepts an input signal and produces an output signal proportional to the input, is called an amplifier. An amplifier which amplifies the difference between the two input signals is called differential amplifier. The differential amplifier configuration is very much popular and is used in variety of analog circuits. The differential amplifier is an essential and basic building block in modem IC amplifiers. The integrated circuit (IC) technology is well known now a days, due to which the design of complex circuits become very simple. The IC version of operational amplifiers is also popular which is inexpensive, takes up less space and consumes less power. The differential amplifier is the basic building block of such IC operational amplifier.
