摘要：

A low-power Variable Gain Amplifier (VGA) is demonstrated in a commercial 0.18 mu m CMOS technology, with a chip size of 0.019mm(2). To compensate the threshold voltage process variation, a control voltage level shift (CVLS) methodology is proposed. The VGA was measured with a dynamic range of 29dB with a +/-0.62dB error. The total power consumption is 186 mu W, and the bandwidth is 26MHz.
