Title: IIP3 and 1 dB Compression point Post by ssk_288 on Oct 18th, 2005, 2:07am Hi Can anyone suggest me some paper which relates the IIP3 and 1 dB compression point to Drain current, gate overdrive etc.... for a LNA Thanks Regards SUDHIR |

Title: Re: IIP3 and 1 dB Compression point Post by RFICDUDE on Feb 27th, 2006, 6:42pm The main reference for the CMOS IP3 is not correct in the refered website document. Here is link to the author's presentation (Thomas Lee's Standford group) http://www-smirc.stanford.edu/papers/cancun97s-chet.pdf And here is the paper http://www-smirc.stanford.edu/papers/cancun97p-chet.pdf Also note that the web paper on LNA's is about differential LNAs, but the IP3 paper is on short channel single ended MOSFETs. There was also a good characterization paper at RFIC 2005 on linearity of short channel MOSFETs.
