Abstract
This VGA is designed for a GSM subsampling receiver. It operates at an IF frequency of 246MHz. The VGA provides a 60dB digitally controlled gain range in 2dB steps. The VGA is implemented in a 0.35μm CMOS process. The current is 9mA@3V. The overall gain accuracy is less than 0.3dB. The noise figure at maximum gain is 8.7dB. The IIP3 is -4dBm at minimum gain
