摘要: A higher frequency, over 2 GHz, is suggested for current 4G or 5G wideband applications. By adopting a unique gain control method, an analog-controlled variable-gain amplifier (VGA) with accurate dB-linear characteristic presented. The designed VGA not only features large bandwidth, but also has adjustment relatively wide voltage range. measured range of 24 dB, which 17.3 dB less than $\pm$ 0.3-dB error. $-$ 3-dB bandwidth constant from to 2.2 GHz the entire An output 1-dB compression point 1.8 dBm and noise figure are measured. Due simple structure, consumption core 2.9 mA 1.2-V supply, size ${\hbox{225}}\ \mu{\hbox{m}}\times {\hbox{45}}\ \mu{\hbox{m}}$ , excluding pads. Moreover, robustness verified by means Monte Carlo simulation.
