Following table illustrates the difference between MOSFET and BJT. NPN BJTN-channel MOSFET (NMOS) It has three terminals viz. base, emitter and collector It has three terminals viz. Gate, Source and Drain Cutoff region { <VBE(ON) ; <VBC(ON) } Cutoff region { VGS<Vt ; VGD<Vt } ...
MOSFET can be divided into N-channel depletion type and enhancement type; P-ditch depletion type and enhancement type. Fig.2 Some MOSFET have a diode inside, which is a body diode, or a parasitic diode or a freewheeling diode.There are two explanations about the role of parasitic diodes:...
P-channel MOS tube has a low hole mobility, so when the geometric size of the MOS tube is equal to the absolute value of the working voltage, the transconductance of the PMOS tube is smaller than that of the N-channel MOS tube. In addition, the absolute value of the threshold voltage ...

The mos tube is divided into N-channel and P-channel. We use NMOS because it has small on-resistance and is easy to manufacture. As you can see on the MOSFET schematic, there is a parasitic diode between the drain and the source. This is called a body diode, which is important for ...
for current to flow, the FET is of two types viz.N-Channel FETandP-Channel FET. In case of FET, there is no PN junction between the source and drain. The gate region of FET is made from alternate semiconductor material as compared to the channel between the source and drain terminals....
Since PNP and NPN transistors are composed of different materials, how voltage is biased to them to produce current flow is different, and their current flow is opposite as well. PNP transistors are made up of 2 layers of P material sandwiching a layer of N material, while NPN transi...
MOS tubes can be used not only as switching circuits, but also as analog amplifiers, because changes in gate voltage within a certain range will cause changes in on resistance between source and drain. The main difference between the two is: ...

The unit area size of this capacitor is related to the thickness and dielectric constant of the gate oxide. If the gate voltage is a voltage lower than the ground, the N-type channel between the source and the drain cannot be formed at this time, but the holes of the P-type substr...
