Difference Between Bjt And Mosfet Advantages Disadvantages I want to make a mosfet model having the following parameters in ltspice: $$\mu nc {ox} = 100 \mu a v^2 ; v {th} = 0.5 v, \lambda = 0$$ and to define w and l, where i can change it from one design to another. It appears they also wear out much quicker. and solid state relays that i have found so far are generally very large compared to a mosfet or relay and drop a constant voltage up to 1v across them, which would be a big problem for high side switching of say 5v.
Mosfet Working Types Operation Advantages Applications The threshold voltage of a mosfet decreases as temperature increases. i don't understand this. consider an n type mosfet that is fabricated in a p doped silicon substrate. for a channel inversion l. Optional: edit the drawing of the auto generated symbol (e.g. for a mosfet, remove the yellow box and draw a mosfet symbol); it is sometimes useful to hide the pin labels by right clicking the pin and selecting none(not visible). save the symbol file. it is located in documents\ltspicexvii\lib\sym\autogenerated; you can leave it there. I am trying to understand this formula to find the transconductance of a mosfet transistor, but i am not getting the passage from the second to the third line. what happened there? thank you. Questions: 1) how to calculate the mosfet input resistor? 2) what are the factors affecting the mosfet input resistor calculation? 3) what will be the maximum, minimum resistor value possible and effect in the circuit if the resistor value is changed (increased or decreased) ? please let me know if any further info is required.

The intrinsic body diode is the p n junction between the body and the drain. in a discrete (standalone) mosfet, the source and body are usually tied together for convenience to make a three pin package. this means there's a diode between the source and drain: if the source voltage is always lower than the drain voltage, the diode stays off, and everything works as expected. this means you can. 7 it is normal to drive the gate of a mosfet through a resistor (normally under 100r). it is also seen a diode exactly as connected in the schematic. the reason is that the gate is a capacitive load to the driver. this means that is has to charge when turned on, and discharged when turned off. From figure 1 is evident that to get the dead time i must define the values for rc. e.g my resistor is 220 ohms and capacitor is 0.1uf this gives me 22us at 1 time constant, however, when i measure. Can anybody help me understand, what exactly a high side and low side driver is? in which scenario would either of them be used?.
