Multistage (Cascaded) Amplifiers
Learning Objectives
Many performance features of practical amplifiers may not be met with single-stage Amplifiers. Considering the various aspects of single-stage amplifiers, the following aspects of Multistage (Cascaded) Amplifier are discussed:
- Multistage (Cascaded) Amplifier gain and Bandwidth
- Advantages of different coupling schemes of Multistage Amplifiers
- Various schemes of CASCODE Amplifiers
- Cascading amplifier design to obtain ‘Darlington Pair circuits'
- Concepts and design aspects of differential amplifiers.
10.1 CONCEPTS OF CASCADED (MULTISTAGE) AMPLIFIERS
10.1.1 Introduction
The gain of a single-stage Amplifier may not be adequate for certain applications and the input and output impedances ...
