D. Sanchezhernandez et al., CAD TECHNIQUES FOR THE ELECTROMAGNETIC DESIGN OF MONOLITHIC MILLIMETER-WAVE INTEGRATED-CIRCUITS, Annales des telecommunications, 52(3-4), 1997, pp. 164-173
It is well known that mm-waves have an important role to play in the r
apid expansion of mobile and personal communications. MMIC technology
is an important factor since it can provide a means of mass producing
rite user terminal RF subsystems. Millimetre-wave integrated circuits
do not yet however offer the high packing density and functionality wh
ich is now possible for lower frequency applications where lumped elem
ents are used. This problem is influenced most of all by the extreme m
odelling difficulties encountered at frequencies above 30 GHz. This pa
per reviews the current state-of-the-art for CAD techniques used in MM
IC design. It describes some limitations of the standard Smart(TM) lib
rary approach and looks at the application of commercial electromagnet
ic simulators in the design of both microstrip and CPW circuits.
