| contents | Next-generation cellular systems require low-power mm-wave phased-array ICs. Variable-gain LNAs (VG-LNAs) are key blocks enabling reduced hardware complexity, performance improvement and added functionalities. This paper reports a low-power 30GHz VG-LNA for mm-wave 5G/6G phased-array ICs, with a gain control of 8 dB for 18dB Taylor taper in a 30GHz 8x8 antenna array. The VG-LNA exhibits a peak gain of 16 dB in the high-gain state, consumes less than 1 mW and occupies an area of 0.20 x 0.22 mm2. |
