摘要：
This paper describes a CMOS programmable gain amplifier that maintains a 3dB bandwidth greater than 110MHz and can provide 84dB gain control range in 1dB steps. The PGA can also be operated in a low power mode with 3dB bandwidth greater than 71MHz. Integrated with this PGA is a CMOS successive logarithmic detecting amplifier with a +/-0.7dB logarithmic accuracy over 80dB dynamic range. It achieves a sensitivity of -83dBm. The amplifier consumes 13mA from a single 3V supply in high power 2 mode. The chip area including pads occupies 1.5 x 1.5mm(2).
