摘要
In this paper, a novel structure of linear-in-dB gain control is introduced. Based on this structure, a wideband variable gain low noise amplifier (VGLNA) has been designed and implemented in 0.18 μm RF CMOS technology. The measured results show a good linear-in-dB gain control characteristic with 15 dB dynamic range. It can operate in the frequency range of MHz and consumes 30 mW from 1.8 V power supply. The minimum noise figure is 4.1 dB at the 48~860 maximum gain and the input P1DB is greater than - 16.5dBm. Copyright © by HIGN TECHNOLOGY LETTERS PRESS.
