Jin-Siang Syu, Chinchun Meng, Chia-Ling Wang
2011 IEEE transactions on microwave theory and techniques  
A 2.4-GHz low-power low-noise direct-conversion receiver is demonstrated using parasitic vertical-NPN bipolar junction transistors (BJTs) in a standard 0.18-m CMOS process.  ...  When the mixer operates near or higher than the transistor , the loss of the polyphase filter due to the capacitive loading of the mixer is a main issue.  ...  On the contrary, the high-performance, but high noise corner nMOS device can be used in the RF LNA and the RF stage of the mixers because the low-frequency noise at the RF stage will be upconverted to  ...
