“…Therefore, high impedance nodes are avoided, and the noise figure is reduced correspondingly. Compared with the previously published LNAs operating in similar and nearby frequency bands [3][4][5][6][7], measured results show that the proposed LNA has the advantages of flat transconductance gain higher than 17.0 dB and noise figure lower than 2.31 dB. Besides,it operates at low voltage of 0.85 V and only comsumes power consumption of 12.1 mW.…”

“…Although some articles have been reported about current mode LNAs in recent years,few of them are about wide band and IEEE 802.11a LNAs [3][4][5][6][7]. IEEE802.11a system, which is based on Orthogonal Frequency Division Multiplexing (OFDM) modulation, provides nearly five times data rate and as much as ten times the overall system capacity as currently available IEEE802.1lb and 802.1lg systems, is one of the most promising technology in IEEE field and valuable to research.…”

In this paper, a novel current-mode differential transconductance low noise amplifier (LNA) designed in the chartered 0.18 µm CMOS technology is proposed to realize the receiver front-end. The proposed LNA frequency ranges from 4.7 GHz to 6 GHz,mainly targeting at IEEE802.11a application. It utilizes two stage structure, with a PMOS current-mirrorr using inductive series peaking technique to achieve optimized current output. The noise performance is improved through the use of a gmboosting technique, while the gain performance is improved and power consumption is saved by using current-reused technique. Measured results demonstrate that the circuit provides flat transconductance gain higher than 17.0 dB, noise figure lower than 2.31 dB and low operating voltage of 0.85 V in frequency band. A comparison with other LNAs in similar and nearby frequency bands shows the proposed LNA has advantages of higher gain, lower noise figure and better other performances.
