Abstract :
This paper presents a low power high linearity driver amplifier for 900 MHz Zigbee applications based on 0.18 μm CMOS technology. In this work folded cascode amplifier is adopted to get more efficient power transmission. High gain and linearity are achieved by applying resonating load and gain boosting technique. Measurements show 11.5 dB gain, 3 dBm output P1dB while dissipating 1.8mA DC current from 1.8 V supply.
