  • Abstract
    A CMOS baseband amplifier using an open-loop architecture is presented. The eight-stage amplifier, implemented in a standard 0.13 m CMOS technology, shows a maximum gain of 30 dB in the broadband frequency range 20 850 MHz. Each amplification stage draws 0.8 mA from a single 1.2 V power supply. The total amplifier chain shows an output referred OIP3 of 11 dBm, which can be achieved by using active loads that compensate for the nonlinear transconductance of the input transistors.
