摘要: A low power digitally-controlled CMOS variable gain amplifier (VGA) was fabricated in a TSMC 0.18 ?m technology. By extending the transconductor operation range from saturation mode for high to triode gain, proposed VGA can obtain wide with dissipation. The consumption of is as small 2.16 mW while keeping 53 dB. has controlled -22 dB 31 1 steps. When set maximum total harmonic distortion (THD) and 3 bandwidth are -48 at least 65 MHz, respectively.
