What are the applications of jfet?
• High Input Impedance Amplifier. • Low-Noise Amplifier. • Differential Amplifier. • Constant Current Source. • Analog Switch or Gate. • Voltage Controlled Resistor. • JFET as a Switch • JFET as a Chopper • JFET as a Current source • JFET as a Amplifier • JFET as a Buffer
What is working principle of jfet?
no
In a JFET gates are always?
forward bias
A de mosfet differs from a jfet in the sense that it has no?
channel
The voltage of a given common source JFET amplifier is depend on what?
amplification factor
Can jfet operate in enhancement and depletion mode?
No, jfet works only in depletion mode.
How jfet works?
A Jfet works by applying voltage to the drain of the jfet. A jfet will then conduct across from drain to source.
Why jfet is called as junction field effect transistor?
Because the insulation between the gate and the channel is only a reverse biased PN junction. If this junction were to become forward biased the jfet would no longer operate as a transistor at those times.

What type of transistor is a JFET?
JFET is a unijunction transistor.
What is a tuned rf jfet amplifier?
It's a junction gate field effect transistor that has it's bandwidth tuned to operate (amplify) in the radio frequency range.
What is working principle of jfet?
no
Does the channel width of the JFET remains constant at any point of time?
It depends on the topology of the circuit in which the JFET is operating.
In a JFET gates are always?
forward bias
What is mean by BFW10?
its a n channel jfet(field effect transistor) manufactured by Motorola
A de mosfet differs from a jfet in the sense that it has no?
channel
What is the difference between jfet and mosfet?
1-BJT is bipolar while JFET is unipolar. 2-BJT has low input impedence while JFET has high input impedence. 3-JFET has low power discipation as compared to BJT. 4-JFET has low noise as compared to BJT. 5-BJT is current controlled while JFET is voltage controlled. 6-JFET is mostly used in digital circuits.
