The issue about RFIC CMOS design using real component match

[ian227]

Firstly I use the ideal inductor and capacitor to design
Then I instead of real passive component
but the performance change very much
how to use real passive component to simulate CMOS RFIC
I use ADS with TSMC model
The Q of inductor is very low which change with freq. and geometry
I try to use inductorQ with constant Q and then I found it is a wrong method
Please give me a good method to use.
Thanks

The real passive model of the component is close to the real world design. Whatever is the low value of the inductor you have to leave with that, and tune the circuit for those value.
Just a remainder, different shapes of the printed inductor gives different Q values.
