In three stage amplifier the first stage consists of a differential amplifier,second stage consists of a coupling device as a combination of diodes and third stage uses a current limiter. The three stages are: First stage-Differential amplifier, Second stage-Combination of diodes, Third stage-Current limiter I. INTRODUCTION

Need help/resources to understand amplifier design I've been trying to learn how to design a basic 3-stage audio amplifier. I've been referring to Bob Cordell and Douglas Self's textbooks on the topic, but I cant find comprehensive explanations about the design of the basic amplifiers they show in their book.

6. Apr 20, 2012. #1. Hello. I'm currently working on a 3 stage audio amplifier for a project and need some help. The load is a 8 Ω speaker and I need to get a 1V input at a gain of 10. If I'm right, it should work as longer as all the transistors connected are in some kind of operating range. However, the PNP in the current gain stage (lower ...

The first stage should be a long tailed pair. The second stage can be a CE voltage amplifier, and the third stage can be a current buffer (emitter follower). Focus on high gain and biasing for wide Voltage swing. You can set the precise gain with feedback later. Take this for what it is worth.

The amplifier consists of three stages, a low gain degenerated common emitter Q 1, a high gain stage, Q 2 and the push-pull output stage, Q 3 and Q 4. Q 3 and Q 4 are commonly referred to as a push pull configuration. NPN Q 3 sources (push) current to the output load on the positive half cycle while PNP Q 4 sinks current from the load on the negative half cycle (pull).
