Abstract

In this paper, an ultra-wideband Ka-band low-noise amplifier (LNA) is presented using broadband transformer matching and gate-drain feedback technology. The proposed LNA achieves ultra-wideband while maintaining the high integration and low power consumption of traditional source-degenerated LNAs. Additionally, cascading technology is used to increase the peak gain. The proposed LNA is implemented in a 55 nm CMOS process. The simulation results show that the LNA achieves a stable gain response in the frequency band of 21.7-36.5 GHz, and the peak power gain is 20.8 dB. The minimum noise figure is 4.4 dB. The DC power consumption is 15 mW with a compact chip area of 0.33 mm².
