Calculating A FET Gate Resistor Part 1 & The Basics of A FET Transistor (Read 'More')
Hi, a look at the basics of a FET & how to calculate the value of a gate resistor.
You will see the total gate charge required was quoted as 38nC not 9.
However, you will see the ‘charge’ Q (gate to drain) played a large role in the total switching time seen during the Millar Plateau.
You will see the drain voltage came down to zero at the end of the ‘plateau’
I wanted to keep this introduction easy.
It is useless bombarding one (you) with a tonne of information since most of it will not be absorbed.
38nC / 100ns = 380 mA but you will see that time did not play out with the voltage I had on the drain.
Baby Steps :)
