- mosfet - In an NMOS, does current flow from source to drain or vice . . .
Conventional current flows from Drain to Source in an N Channel MOSFET The arrow shows body diode direction in a MOSFET with a parasitic diode between source and drain via the substrate This diode is missing in silicon on sapphire 2a is a JFet so different topology 2d is a MOSFET with no body diode I've never seen one
- How to make a LTspice MOSFET Model?
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 I do not have much knowledge about SPICE modelling commands, and so would appreciate a code or procedure that I can try to use to make
- transistors - Understanding the curves of a MOSFET - Electrical . . .
I am trying to understand the curves of a MOSFET Sorry if the question is very basic Where the red point is is the saturation zone of the MOSFET, therefore the source drain voltage must be 0V because at this point the MOSFET is saturated conduction at maximum current, because on the X axis of the graph called Vds marks 10V for the red point
- transistors - MOSFET Power Supply Explained - Electrical Engineering . . .
The MOSFET is not amplifying voltage or current It is regulating the output voltage to be constant under various loads Z1 is the voltage reference and Q1 and Q2 compare Z1 with the voltage set by the divider R3 and R7 A MOSFET is used due to its low ON resistance
- What is the difference between MOSFET transistor and normal transistor . . .
[From Question]: MOSFET transistor and normal transistor A MOSFET is a normal transistor - it's a Metal-Oxide-Semiconductor Field-Effect Transistor A BJT is another normal transistor - a Bipolar Junction Transistor The question itself doesn't make much sense in that regard But lets assume for now you mean BJT when you say "normal"
- mosfet - High side driver and Low side driver - Electrical Engineering . . .
Since the gate of the MOSFET has to be V\$_{GS}\$ volts higher than the source, a special IC is needed to translate the logic level at the CTL lead into the much higher gate voltage Even if the N-channel was being used in a low-side configuration, the driver chip would be needed to properly drive the gate fast enough
- mosfet - Vdss, Vds(max), BVdss and Vgss, Vgs(max) - Electrical . . .
It seems that unfortunately different manufacturers use slightly different notation Usually V_DSS or V_DS(max) are the maximum allowable Drain-Source voltage according to manufacturer datasheet, the same for V_GS(max) but for Gate-Source voltage
- mosfet - Is there an equation to calculate the voltage spike caused by . . .
I am using a MOSFET as a low side switch If I do not use a freewheeling diode to discharge the energy stored in the inductor, what is the numerical value of the spike cause at the intersection node of the inductor and the drain of the low side N-channel MOSFET when it is turned off? Is there an equation describing this? Diagram given below
- How are MOSFET gate capacitances (Cgs, Cgd) calculated?
Keep in mind that the physical mosfet is a symmetric device In the case of N-MOS, the terminal with a lower voltage is called the source (since it sources the charge carriers i e electrons) and the terminal at the higher voltage is called the drain
- mosfet - How to do high voltage high-side switching in a simple and . . .
Initially it seemed like the obvious choice for a switch would be a logic level N channel power mosfet in low-side configuration This is because they do not draw current in order to keep them switched on or off, have a very low resistance so waste a low amount of power, and in low-side config can be driven by either the ESP32 GPIO or via a
