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 …
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.
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 …
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 …
MOSFET symbol - what is the correct symbol - Electrical Engineering ...
May 14, 2013 · I've been on this site now a couple of months and I notice various symbols used for MOSFETs. What is the preferred symbol for an N Channel MOSFET and why?
When is a MOSFET more appropriate as a switch than a BJT?
For an N-channel MOSFET (NMOS), for instance, which can switch current from Drain to Source, the body diode goes in the opposite direction, pointing from Source to Drain. So, feel free to take …
