What is bjt and jfet?
BJT is Bipolar junction transistor FET is Field effect Transistor It is a current controlled device It is voltage controlled device
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.
Which are preferred from both unilateral and bilateral tolerance system?
unilateral
What is mean by BFW10?
its a n channel jfet(field effect transistor) manufactured by Motorola
Why is JFET used as an input device?
it has high input impedance
What are current controllable devices?
BJT is a example for current controll device. And JFET is a voltage controlled device.

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.
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.
When you post a message where does the message go?
The message goes through unilateral wires to another person's device.
Can jfet operate in enhancement and depletion mode?
No, jfet works only in depletion mode.
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.
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.
Why the n-jfet is operated with the negative voltage not the positive voltage?
In a JFET the only insulation between the gate and the channel is a reverse biased diode junction, if this junction becomes forward biased then the gate and channel are effectively shorted and the device no longer acts as a transistor (it will act as a forward biased diode instead). In the n-channel JFET, the gate is the P-side of this diode and the channel is the N-side of this diode. To keep this diode reverse biased (and the device operating as a transistor) therefor the gate MUST always be maintained at a voltage more negative than the most negative section of the channel.
