A 7.9-mW 5.6-GHz digitally controlled variable gain amplifier with linearization

This paper presents the design and validation of a compact high-performance digitally controlled variable-gain amplifier (DVGA). By using MOS switches and a linearizer, the designed DVGA demonstrates high linearity and gain flatness over a wide gain control range. The 6-bit DVGA is designed in a com...
