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.
Can jfet operate in enhancement and depletion mode?
No, jfet works only in depletion mode.
What is mean by BFW10?
its a n channel jfet(field effect transistor) manufactured by Motorola
Why is the input impedance of a jfet so high?
If you mean JFET, it is because the gate junction is reverse biased.
Why should a JFET be operated with only reverse bias on the gate?
If the gate-channel junction of a JFET was not reverse biased the JFET would just act as a forward biased diode across that junction and the gate would cease to have any control over the channel conductance. For the same reason in a MOSFET the substrate-source/channel/drain junction must remain reverse biased. The MOSFET could not act as a MOSFET.

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 type of transistor is a JFET?
JFET is a unijunction transistor.
Can jfet operate in enhancement and depletion mode?
No, jfet works only in depletion mode.
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.
A JFET can operate in?
active region.
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.
Why is the input impedance of a jfet so high?
If you mean JFET, it is because the gate junction is reverse biased.
