摘要

提出了一种高频、高动态范围的CMOS可变增益放大器(VGA)。它有一个可控的增益范围从-45分贝到+45分贝的外部控制电压，以及增强的工作频率高达200 MHz。采用0.35 /spl mu/m CMOS工艺制作，核心面积580 /spl mu/m/spl倍/660 /spl mu/m。它在3.3 V电源电压下仅消耗10.8 mA。

A 200 MHz/90 dB gain range CMOS VGA

A novel CMOS Variable Gain Amplifier (VGA) with high frequency and high dynamic range is proposed. It has a controllable gain range from -45 dB to +45 dB by external control voltage as well as enhanced operating frequency up to 200 MHz. It is fabricated in 0.35 /spl mu/m CMOS technology with the core area of 580 /spl mu/m/spl times/660 /spl mu/m. It consumes only 10.8 mA at 3.3 V supply voltage.
