This project analyzes and studies the JFET as an amplifier. It will compare the JFET to the BJT, analyze the input and output characteristics of the JFET amplifier through simulation, and examine the important components needed for the JFET to function as an amplifier. Simulations will be performed on CircuitLab, and research from papers and online sources will provide the theoretical background. The JFET is chosen because it is more temperature stable, smaller, less noisy, and has higher input impedance than the BJT.

1. PROJECT
Tittle
JFET as an Amplifier

2. ABOUT PROJECT
In this project we are going to analize and study , jfet
as an amplifier and make a final report in which all the
required comparison with bjt , input and output
characterstics of amplifier ( jfet) ,simulation analysis
and importance of components required to work jfet
as amplifier.

3. REQUIREMENTS:
�We will perform simulation on
CircuitLab(Analog & digital circuit
simulator)
�For content required to address theoritical
aspects some reserach papers and online
things are used.

4. Why JFET
?
As JFET is field effect transistor so :
• More temperature stable than BJT
• Smaller than BJT’s
• No junctions so Less noisy than BJT
• High input impedance i.e drawback of BJT
