Abstract :
This paper presents a dual-path noise-cancelling (DPNC) LNA, which is designed for low power wireless sensor network (WSN) applications and operates at 2.4GHz band. The proposed DPNC LNA can effectively cancel internal circuit noise while consuming less power by gm-boosted technique. The measured voltage gain and NF are 22dB and 3.7dB, respectively. IIP3 is +8dBm and consumes 1.2mW with a 1.0V single supply. Fabricating in the 0.18μm standard CMOS process, the LNA occupies an active area of 0.3mm2.
