Michael and Arpad The arrows correspond to the transistor terminals before the circle was added and not to any direction flows. So these should be just terminals without reference to NMOS or PMOS or generically the practical case of parallel NMOS and PMOS configurations. The current flow arrow defines the sign convention for all cases.

Thanks, Arpad ================================================ From: ibis-editorial-bounce@xxxxxxxxxxxxx [mailto:ibis-editorial-bounce@xxxxxxxxxxxxx] On Behalf Of Mirmak, Michael Sent: Wednesday, March 07, 2012 12:41 PM To: ibis-editorial@xxxxxxxxxxxxx Subject: [ibis-editorial] Figure 38 has both arrows... and is accurate to the original source In a previous meeting, we noted that the Series MOSFET extraction diagram, Figure 38 in the current drafts, shows two different arrows pointing in opposite directions (one at the source and one at the drain). Unfortunately, the original IBIS 5.0 document, on page 179 of Section 9, contains an ASCII drawing for this same structure with two arrows pointing in opposite directions. What *should* this diagram show? - MM
