A low-power Variable Gain Amplifier (VGA) is demonstrated in a commercial 0.18µm CMOS technology, with a chip size of 0.019mm2. 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 186µW, and the bandwidth is 26MHz.
