摘要：

A transformer feedback low-noise amplifier (LNA) is implemented in a standard 0.18 mu m CMOS process, which exploits drain-to-gate transformer feedback technique for wideband input matching and operates across entire 3 similar to 5 GHz ultra-wideband (UWB). The proposed LNA achieves power gain above 9.5 dB, input return loss less than 15.0 dB, and noise figure below 4.8 dB, while consuming 8.1 mW from a 1.8-V supply. To the authors' knowledge, drain-to-gate transformer feedback for wideband input matching cascode LNA is the first adopted technique for UWB application.
