2 Stage Amplifiers: Amplifier has a wide range of applications in real life devices such as Audio Amplifiers in your electric guitar, Analog to Digital Converters in your cell phone's communication network, hearing aids and many more.
2 Stage Amplifier Circuit using Transistors - Gadgetronicx
https://www.gadgetronicx.com/2-stage-amplifier-circuit-transistors/
This 2 stage amplifier circuit comprises of two stages each of which perform amplification on the incoming audio signals and output finally obtained at the end of 2nd stage. A simple Microphone was used to feed input audio signals followed by a coupling capacitor C1 which removes any DC element from audio signal.

Sketch the circuit of a two-stage internally compensated op amp with a telescopic cascode first stage, single-ended output, tail current bias first stage, tail voltage bias second stage, p-channel inputs and n-channel
ECE 3274 Two-Stage Amplifier Project 1. Objective
http://www.courses.ece.vt.edu/ece3274/twostage.pdf
The CS-CC cascade two-stage amplifier is a good multistage configuration because the CS and CC amplifiers together provide some very desirable characteristics. The CS amplifier makes up the first stage and is capable of providing high voltage gain. The input impedance of the CS is a function of Rg1 and Rg2 and is generally very high.

A two-stage operational amplifier consists of a differential amplifier at the input stage, while the second stage is a high gain stage biased by the output of the differential amplifier. As explained before, two-stage operational amplifier exhibits two poles below the unity open-loop gain. As shown on figure 3, when the gain of the two-stage operational amplifier
Stage Amplifier - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/engineering/stage-amplifier
The second op amp is powered from a positive supply and furnishes a positive output voltage for increasing load current. A dual op amp cannot be used for this implementation due to the different supply voltages for each stage. This circuit is exceptionally precise due to the use of zero-drift op amps. The scaling accuracy is established by the quality of the user-selected …
