i have designed a filter with two spiral inductor in it for 2.5GHz application. When i simulate the whole layout with inductors in ADS (Momentum Microwave), the results didnt correlate with circuit simulation.
i re-simulated standalone inductor and compared the results with MSIND (TLines-Microstrip). No correlation between MSIND and the layout simulation so the problem is the spiral inductor.
i would like to know the optimum layout simulation settings for spiral inductor in order to obtain good correlation between MSIND and the layout. Take note that i have created the inductor from the MSIND so the layout simulation should correlate with circuit.
my spiral inductor (MSIND) is very compact. the parameters are:
N=17.7243
Ri=45.7773
W=9.75086
D=6.35643
im also thinking its not practical to simulate the whole layout together with the inductor using Momentum Microwave. its because its time consuming. its better to simulate the inductors separately and the connect them toegther in layout look-alike component. Please let me know your thought about this.
thanks.
