Multistage amplifier report
Due to its low cost and excellent audio fidelity over a wide range of frequencies, an RC Coupled Amplifier is the most popular type of coupling used in a multi stage amplifier. As you can see in the fig above, a coupling capacitor C C is used to connect the output of first stage to the base i. Since here the coupling from one stage to next is achieved by a coupling capacitor followed by a connection to a shunt resistor, therefore, such amplifiers are known as resistance-capacitance coupled amplifier or simply RC coupled amplifier. The resistances R 1 , R 2 and R E form the biasing and stabilisation network. The emitter bypass capacitor offers a low resistance path to the signal.

Explain Working of RC Coupled Amplifier
RC coupling is the most widely used method of coupling in multistage amplifiers. In this case the resistance R is the resistor connected at the collector terminal and the capacitor C is connected in between the amplifiers. It is also called a blocking capacitor, since it will block DC voltage.
The main disadvantage of this coupling method is that it causes some loss for the low frequency signals. However, for amplifying signals of frequencies greater than 10 Hz, this coupling is the best and least expensive method. It is usually applied in small signal amplifiers , such as in record players , tape recorders , radio receivers , etc. From Wikipedia, the free encyclopedia.

Chapter 15 Multistage Amplifiers
The power gain otherwise voltage gain can be achieved by the single-stage amplifier but it is not enough in practical application. For that, we have to use multiple stages of amplification for achieving the required voltage gain or power. This kind of amplifier is termed as a multistage amplifier analysis. In this amplifier, the first stage output is fed to the next stage input. Such type of connection is commonly known as cascading. This article discusses an overview of the multi-stage amplifier and its frequency response. Based on the kind of amplifier used within separate stages, these amplifiers are classified into different types.
Multistage Yb-doped fiber amplifier generating megawatt peak-power, subnanosecond pulses
There are several advantages with multistage amplifiers, notably achieving high gain with good frequency response and low level distortion. The amplifier we are going to design is a simple cascade connection where four identical stages are connected by RC coupling. In other words we are connecting each stage by using a capacitor in series between the output of the previous stage with the input of the next one. However, the value of each stage gain must consider the loading effect. This is the effect of the input impedance of the next stage against the gain of the previous one. In order to get the input impedance high enough we will set a collector current I C as low as possible; 1mA will be sufficient. We will supply this amplifier with a 12Vdc power supply. The 2N is an epitaxial planar NPN, general purpose transistor for small signals and switching application.

Multi Stage BJT Amplifier
The term amplifier as used in this chapter means a circuit or stage using a single active device rather than a complete system such as an integrated circuit operational amplifier. An amplifier is a device for increasing the power of a signal. This is accomplished by taking energy from a power supply and controlling the output to duplicate the shape of the input signal but with a larger voltage or current amplitude. In this sense, an amplifier may be thought of as modulating the voltage or current of the power supply to produce its output. The basic amplifier, figure 9.

Abstract - The performance obtainable from a single-stage amplifier is often insufficient for many applications, so several stages may be combined forming a multistage amplifier. These stages are connected in cascade, i. The overall gain of a multistage amplifier is the product of the gains of the individual stages.
