• 論文の詳細を見る

• This Paper presents the design of a wideband variable gain amplifier (VGA) using 0.18µm standard CMOS technology. The proposed VGA realizes wideband flat gain using wideband flat negative capacitance. It achieves a 3dB gain bandwidth of 1GHz with a maximum gain of 23dB. Also, it shows P1dB of -33 to -6dBm over the gain range of -28 to 23dB. The overall current consumption is 5.5mA under a 1.5V supply.
