其实CMOS以前主要是用在digital & analog design上面的。后来因为成本问题,siGe, GeAs 都是要求高技术而且yield 很低,成本太高。最主要的是无法SoC...现在越来越多的人都在研究CMoS SoC solution,特别是在submicron CMOS technology,现在的CMOS transceiver 已经很多在手机等产品中引用了。搂主这么说好像不太对。小弟愚见。
p.s. I graduated in July 2006. My final year project was on UWB transceiver design. I think RF design is really very very challenging. It is different from analog or digital. currently I am working as a stupid poruduct engineer in ST... This July I will go back to my uni to do a PhD study in RF IC design.
