Mathematical Analysis  

MOSFET I-V characteristics:

In this applet, the drain current is calculated as a function of Vds and Vgs using the following parameters (Present I-V does not follow this, but will be changed to these shortly, 6/8/98).

The device transconductance k = k' (W/L) is therefore

In the triode region (linear region),

In the saturation region,

Note that, in this aplet the Threshold Voltage is assumed to be constant. The effect of body-bias, Vsb, will be treated in a separate applet using
