What are the advantages and disadvantages of JFET (junction field effect transistor)?

Advantages:

There are some advantages of JFET which are given below,

• The JFET has high input impedance.
• The JFET can be fabricated in small size area.
• It is a majority charge carrier device, hence it has less noise.
• It is a low power consumption device.
• It can be fabricated in small size area.
• It occupies less space in circuits due to its smaller size.
• It has a negative temperature coefficient of resistance, so they possess higher Temperature Stability.

Disadvantages:

There are some disadvantages of JFET which are given below,

• The main disadvantage of the JFET is the relatively low gain bandwidth product.
• The performance of JFET goes downs as frequency increases due to feedback by internal capacitance.
