How to properly drive an N-Channel mosfet with an ESP32
Oct 13, 2025 · From this YT video I learned that above certain loads for a P type mosfet the circuit has to change but I am using an N type so it should be fine. Also that after certain frequencies the mosfet …
transistors - Understanding the curves of a MOSFET - Electrical ...
Mar 10, 2021 · 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 …
Why does MOSFET pinch-off occur? - Electrical Engineering Stack …
This question is about enhanced n-type MOSFETs. From what I understand, an inversion layer is formed underneath the insulating layer below the gate of the MOSFET when a voltage is applied to …
circuit analysis - MOSFET Transconductance - Electrical Engineering ...
Aug 5, 2025 · I’ve come across three different formulas for calculating the transconductance (gm) of a MOSFET. While analyzing a cascode amplifier under DC conditions, each formula yields a different …
What is the difference between MOSFET transistor and normal …
Jan 19, 2019 · 16 [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 …
How should I understand the intrinsic body diode inside a MOSFET?
Aug 5, 2018 · 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 …
P channel MOSFET for Reverse polarity Protection
Aug 29, 2025 · I was trying to understand the reverse polarity protection circuit using a P-channel MOSFET. I understand the purpose of adding a Zener diode: for instance, if our supply voltage is …
How are MOSFET gate capacitances (Cgs, Cgd) calculated?
6 Your equations are approximations to the capacitance seen between G-D and G-S of a mosfet in different regions of operation and they are derived based on the physical characteristics of the …
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.
MOSFET as a Switch - When is it in Saturation?
A bipolar transistor (and NOT a MOSFET) is "in saturation" when it is turned hard on. The equivalent condition in an enhancement mode MOSFET (the most common kind) is when it is "fully enhanced" …
