VARIABLE GAIN AMPLIFIER AND METHOD FOR ACHIEVING VARIABLE GAIN AMPLIFICATION WITH HIGH BANDWIDTH AND LINEARITY

摘要

granularity (fine granularity), widely variable gain amplifier (variable gain amplifier; VGA) is the gain of the VGA In order to adjust the attenuator, a high gain signal path, a low gain signal path and a gain adjustment control, and the gain adjustment control is at least a portion of the low gain signal path or the high gain signal path to achieve a desired overall gain It is configured to cause the selective activation.
