Abstract
This study presents a high performance K-band low noise amplifier. By utilizing transformer feedback at the input stage, an excellent noise figure (NF) of 4.3 dB is obtained at 22 GHz. With the current-reused technique between the two stages, the amplifier achieves a maximum power gain of 10.1 dB under a supply voltage of 1.8 V and a power consumption of only 7.2 mW. The proposed LNA has comparable NF and gain, while it can operate under the lowest power among the published works in 0.18 mum CMOS technology for K-band applications.
