Elmer: Re: "It is the effective length of the channel between the source and drain. It is measured indirectly, thus the term "effective" as opposed to a direct measurement such as the "drawn" channel length." Actually, it is an "effective" channel length because the source and drain areas encroach underneath the gate (due to dopant diffusion and usually 45 degree implants) and is thus smaller than the drawn gate length (not the drawn "channel" length). It's not because of how it is indirectly measured electrically . Regards, Shane
