- 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
- 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 - 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
- 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
- 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"
- Building a MOSFET current mirror - Electrical Engineering Stack Exchange
For the left MOSFET, that is simply achieved by connecting gate and drain: if the gate source voltage is too small to admit the current, the gate will rise in voltage with the drain until it isn't If it is too large for saturation at the given current, voltage will fall until the channel is pinched off to saturation
- mosfet - How can I do a heatsink calculation and determine whether a . . .
The power dissipated by the MOSFET is P = I 2 X R; I is the load current of electric door = 1 2 A; R is the R ds(on) of the MOSFET = 0 035 Ω This gives me a power dissipation of P = 1 2 A X 1 2 A X 0 035 Ω = 0 0504 W
- diagram - How do I do a basic MOSFET wiring? - Electrical Engineering . . .
Ignoring most of them, the simplest is a Mosfet as a switch simulate this circuit – Schematic created using CircuitLab A N-Channel as a Low Side, Active High switch, or a P-Channel as a High Side, Active Low switch
