- Abstract
- This paper presents a novel topology of low-noise amplifier (LNA) with noise reduction and gain improvement. A transformer feedback gm-boosting technique is proposed in a single-ended cascode LNA to reduce the noise figure (NF) and improve the gain simultaneously. Two 54 GHz single-ended cascode LNAs, with transformer and transmission-line for matching, respectively, are demonstrated to verify this technique. Fabricated in a 65 nm CMOS process, the transformer-based (TF-based) LNA exhibits a minimum noise figure (NF) of 3.6 dB at 53.5 GHz and a highest power gain of 28.2 dB at 54 GHz in measurement. To our best knowledge, this LNA has the best noise figure and power gain among all the published V-band CMOS LNAs. The transmission-line-based (TL-based) LNA exhibits a minimum noise figure of 3.8 dB at 53.9 GHz and a highest power gain of 25.4 dB at 54.2 GHz in measurement. Both the LNAs consume 18 mA from a power supply of 1.1 V.
