Abstract

This paper presents a wideband simultaneous noise and input matching (SNIM) low-noise amplifier (LNA) with load regulation and gm-boosting techniques based on a reversed low power three-stage current-reuse topology. Based on magnetically coupled resonator (MCR), the load regulation technology also reduces the high frequency noise and extends the response bandwidth of the gain. Fabricated in 55-nm CMOS technology, the LNA achieves a measured power gain of 16.5 dB at 28 GHz with a -3-dB bandwidth (BW) of 8.8 GHz. Within the entire band of interest, the measured noise figure (NF) matching (NF-NFmin) is less than 0.2 dB and NF falls within the range of 4-4.5 dB. The LNA consumes only 3.38 mW from a 1.2-V supply, with a chip area of 550μm × 570μm.
