1 In Thoms LEE's book , he suggests a inductively source degenerated LNA to minimum the noise figure, when he get a equation of input impedance including Cgs consideration whereas omitting Cgd, why Cgd is omitted, is it far smaller than Cgs in some simulation, Cgd is in the same quantity as Cgs, especailly in CMOS technology.
2 In IEEE ISSCC 2002, a paper is called Noise Cancelling in Wideband CMOS LNAs is submited, author is F. Bruccoleri, Klumperink , Nauta, they suggest a technology to cancel the noise to minimum NF, The LNA operats at the frequency between 2 to 1600MHz, NF is 2 dB.
I want to know How random thermal noise and flicker noise can be canceled in time region and frequency region, thanks
