2.4-GHz Low-Noise Direct-Conversion Receiver With Deep N-Well Vertical-NPN BJT Operating Near Cutoff Frequency
2011
IEEE transactions on microwave theory and techniques
Preserved Fulltext
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 ...
