I am a newbie of RFIC design. I have chosen the CMOS LNA topology according to the design specification, which is the cascode amplifier with source degeneration. But how can I begin my design and parameter optimization using Cadence Spectra? Where can I find a detailed step-by-step procedure for LNA design? Please give me some advices. Thanks!
I have read some books and papers about CMOS LNA design theory, but I still can not set about it. So I think what I need most is a simple step-by-step design example.
The project I am doing now is CMOS LNA, which is a little different from the traditional microwave LNA design. For example, I have to decide the size of the mos transistor. So I think it may be better if I can find a detailed design example. however, most textbooks just cover a lot of similar LNA theory.
guys, if you have read some materials about COMS LNA, such as Thomas Lee's paper, you can start your design following by it. By the way, to kella, i have read www.rfic.co.uk about LNA design, there is a little difference between it and Thomas Lee's suggestion, can you explain it in detail, thanks a lot!!
to xuebi, and you can simulate your design step by step according to spectreRF.pdf. it is in cadence help document

Shaeffer correct the Q value to 2.6 for fixed Pd optimization topology in Jun, 2005. During these 8 years, nobody noticed that the Noise factor equation is wrong...
