A novel CMOS variable gain amplifier (VGA) with high frequency and high dyn
amic range is proposed. The VGA has a controllable gain range of -50dB - +5
0dB which can be controlled by adjusting the external voltage as well as an
enhanced operating frequency range up to 200MHz. It is fabricated using 0.
35 mu m CMOS technology and has a core area of 580 x 660 mu m.
