Yeah that was disappointing. Coco should stick to writing his own jokes.

"How do you find the gm of a MOSFET using graphs on the datasheet?"
The transconductance (gm) of a MOSFET can be found from the datasheet by using the following method:

Look for the transfer characteristic graph on the datasheet, which plots the drain current (Id) versus the gate-source voltage (Vgs) at a fixed drain-source voltage (Vds).

At a specific Vds, usually at the Vds = Vds(max), locate the point on the graph where Vgs = Vgs(th) (threshold voltage) and determine the corresponding drain current, Id(th).How do you find the gm of a MOSFET using graphs on the datasheet?

At a specific Vds, usually at the Vds = Vds(max), locate the point on the graph where Vgs = Vgs(th) (threshold voltage) and determine the corresponding drain current, Id(th).

Calculate the slope of the transfer characteristic curve in the linear region of operation. The slope is equal to the transconductance (gm) of the MOSFET. The slope can be calculated by taking the derivative of Id with respect to Vgs, or by simply taking the ratio of the change in Id over the change in Vgs.

The transconductance (gm) is given by the following equation:
gm = (dId/dVgs) = (Id - Id(th)) / (Vgs - Vgs(th))

Note that the above explanation is for the ideal case, in practice, the gm value can be extracted from a graph by looking at the slope of the curve in the linear region of operation. Also, be aware that the value of gm will vary with Vds and temperature, so you should check that the value of gm you are using is appropriate for your intended application.

That's pretty much how you do it, boys.

coco2.0 will be out soon, and will replace all functions done by the original.

Because they're extinct!

Ooohhhhhh, that's deep. The extinction of the dinosaurs made possible the juice that's powered our cars for the last hundred years.
