Abstract

This paper presents an enhancement-mode (E-mode) Gallium Arsenide (GaAs) 0.15-um pseudomorphic high-electron-mobility transistor (pHEMT) low-noise amplifier (LNA) which employs a positive gate bias condition. Under the 3-dB bandwidth of 8.9 to 17.3 GHz, the proposed LNA achieves a peak gain of 20.7 dB with a noise figure (NF) ranging from 0.75 to 1.5 dB. The measured input-referred 1-dB compression point (P1dB) is -11.9 dBm. The LNA consumes 34.8 mA from a 3 V supply and occupies a die area of 1.44
