For this simple linear regulator:
http://www.candlepowerforums.com/vb...-Simple-Power-MOSFET-Linear-Current-Regulator
The description says that you want NMOS Q1 to operate entirely in the linear region. Since this circuit is designed to be a constant current source to a load, don't we want the transistor to operate in saturation? That is, a constant current irrespective of VDS variation.
Or is the 'linear' description more to do w/ the fact that this circuit dissipates power (ala resistor)?
