Abstract :
This paper presents a CMOS programmable gain amplifier (PGA) with 3dB bandwidth greater than 290MHz. The PGA can provide 50dB gain with 20dB gain control range, and the gain step is ldB with -0.4 to +0.4dB gain error. The minimal acceptable input signal is -52dBm and the 1dB compression point is -6dBm. It consumes 4 mA in core stage from IV supply voltage. This PGA is fabricated in 90nm CMOS one-poly nine-metal digital process and the core area is 0.2x0.15 mm2.
