Abstract :
In the 2.4 GHz IEEE 802.15.4 standard, the noise figure (NF) requirement can be relaxed to minimise power consumption. A fully differential gm-boosting common-gate (CG) low-noise amplifier (LNA) with a series inductor input matching network is proposed. The LNA consumes less than 1 mA from 1 V power supply and achieves a measured gain of 15.5 dB. The series inductor input matching CGLNA is attractive for low-power fully integrated applications in CMOS technologies.
