里面写了这个的技术是differential pair linearization by local feedback,就按照这个关键词查查就能查到相关的文章了,然后还有一个网站时connected paper好像,把你查到的文章的参考文献或者名字放在这个connected paper里面,一大堆相关的文章就出来了
1. Linearization Technique for Source-Degenerated CMOSDifferential Transconductors
2. A HIGHLY LINEAR CMOS AMPLIFIER FOR VARIABLE GAIN AMPLIFIER APPLICATIONS
上面两个是论文的名字,用的关键词是transconductance linearization / lsource degeneration这样,你试试看
