Cascade Amplifier 6

Differential Amplifier:- Differential Amplifier is a device that is used to amplify the difference in voltage of the two input signals. Differential Amplifier is an important building block in integrated circuits of analog system. Advantages of Differential Amplifier: 1. Differential Amplifier has noise cancellation property. 2. Differential Amplifier can reduce external interference. 3. The nature of these amplifiers is linear. 4. These amplifiers help to increase CMRR(Common Mode Rejection Ratio) which further helps to avoid unwanted signal. Disdvantages of Differential Amplifier: 1. Complexity 2. Proper biasing needed
