【 摘 要 】

References(5)Cited-By(1)An intermediate frequency (IF) linear-in-dB variable gain amplifier (VGA) for a radio receiver is fabricated in 0.15-µm fully-depleted (FD) SOI CMOS technology. The complete VGA consists of two stages of the modified linearized transconductance VGA, three stages of fixed gain amplifier (FGA) and a buffer. It provides a continuous -13.6dB to 55.8dB gain control range, an IIP3 of -13.55dBm and an NF of 13.3dB at 100MHz. The proposed VGA using FD SOI CMOS process has great advantages in power consumption and frequency response compared to the bulk CMOS VGA.
