• transformer feedback

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 mu m CMOS technology for K-band applications.
