Abstract

In this paper, a simple CAD formula for microstrip line on lossy substrate of two layers (e.g., silicon-oxide and silicon of CMOS) is obtained through derivations by synthetic asymptote. Synthetic asymptote has been used recently to generate formulas in microwave. The formulas obtained by synthetic asymptote are simple, accurate (error < 2%) and therefore give good physical insights. With synthetic asymptote and image theory, CAD formulas for microstrip line on two-layer substrate were derived. This paper is an improvement, that is: simpler CAD formulas using only synthetic asymptote and no image; this lifts the restriction that the first substrate layer has to be very thin
