Abstract :
This paper demonstrates the use of ADS Momentum to model spiral and straight line inductors for ultra wide band (UWB) applications over a silicon substrate. The main focus is on the improvements in the most recent version of the Advanced-Design System (ADS 2003C), which employs a new algorithm to model metal thickness. Results for two different inductor topologies show the increased accuracy of using a thick metal approach, versus that of sheet conductors, when compared to measured test site data.
