A compact digitally-controlled single-stage variable gain amplifier (VGA) is introduced, which doubles the dB-linear range through the reconfiguration, saves power by 50% while maintaining the same linearity performance compared to those of the previous design. Implemented in 0.18 mum CMOS technology, the 5-bit digitally-controlled VGA achieves dB-linear gain range of 42 dB (-21 to 21 dB) with gain error less than plusmn0.55 dB, bandwidth of 84 MHz at maximum gain of 21 dB and maximum IIP3 of 14 dBm while consuming only 760 muA from a 1.8 V supply.
