Difference between mosfet and fet Mosfets are one type of fets. Fets in general are field effect transistors, which means that they are controlled by an electrostatic field induced by the
Which one is faster: BJT or MOSFET?
it really depends on the application. with progress made in cmos past 15 years or so. bjt is only used in rf front end, with decreasing application space for bjt
What is the reason for reverse saturation current?
In a PN junction diode, the inverse saturation current is due to the diffusive flux of the minorities electrons from the p-part to the n-part and the minor holes from
Why JFET is always reverse biased?
Reason for JFET is always reverse biased Due to “depletion region” surface reduction increases the resistance of the drain source and reduces the current flow and so JFET is always reverse biased.
What will happen if the positive VGS (voltage across the gate and source) is applied to the JFET?
Why vgs is negative in jfet (Junction field effect transistor) The main function of jfet is to modulate the current between the channel and the source with the variation of
How does a PTC relay with capacitor work?
PTC relay A PTC relay means positive temperature coefficient is a starting device for refrigerator compressors. It is responsible for providing power to the start winding for a brief moment to
What are the advantages of FET over transistor?
Advantages of fet over bjt In This post we are going to learn about what are the advantages and disadvantages of FET over transistor. Advantages of fet An advantage of
What is the difference between photodiode and photocell?
Photodiode is A photodiode is a semiconductor device that converts light into electrical current. The current is generated when photons are absorbed in the photodiode. Photodiodes can contain optical filters
What are the differences between UJT and FET
Differences between UJT and FET. ujt (transistor at a junction): it is a transistor with a single junction and three terminals: a transmitter (e) and two bases (b1 and b2).
What is the difference between enhancement and depletion Mosfet?
Difference between enhancement and depletion type mosfet Depletion mode MOSFET is normally turned on at zero gate voltage. Such devices are used as load resistors. MOSFETs with enhancement modes are
What is the pinch off voltage for a JFET?
Pinch off voltage “Pinch-off” is not locked. During pinch-off operation, the discharge current does not drop to zero. Instead, the Id current becomes constant, remaining relatively independent of the Vds
Why is silicon preferred over germanium when producing diodes?
Silicon crystals have less free electrons than germanium crystals. However, silicon crystals can not easily be damaged by excessive heat. Peak inverse voltage ratings of silicon diodes are larger than
Function of inductors and capacitors
Function of inductors and capacitors Both are energy storage devices that store energy and perform various functions in electrical and electronic circuits. Differences between them are as follows: Capacitor is
