Abstract :
Channel resistance cannot be ignored when CMOS circuits operate at radio frequency (RF). Low noise amplifier (LNA) is a very important block in CMOS RF transceiver. The impact of channel resistance on the noise performance of LNA is thoroughly studied and analyzed, and new formulae are proposed systematically in this paper. Furthermore, revised noise figure optimization technique is presented. All of this work will be very instructive for the design of high performance LNA.
