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 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 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.
A JFET can operate in?
active region.
What are the applications of jfet transistor?
The Junction Field Effect Transistor (JFET)exhibits characteristics which often make it more suited to a particular application than the bipolar transistor. Some of these applications are: - High Input Impedance Amplifier - Low-Noise Amplifier - Differential Amplifier - Constant Current Source - Analogue Switch or Gate - Voltage Controlled Resistor
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 fet and ujt?
The structure of a UJT is quite similar to that of an N-channel JFET. The main difference is that P-type (gate) material surrounds the N-type (channel) material in case of JFET and the gate surface of the JFET is much larger than emitter junction of UJT.
