Abstract
This paper presents two differential driver amplifiers designed for low power, low voltage, short-range wireless transceivers working at 2.4GHz band for the personal digital communication. They are fabricated in 0.18 mu m CMOS technology. The one-stage and two-stage driver amplifier provide 14.2dB and 24.4dB gain respectively. The 1-dB output compression point of 4.3dBm and 4.5dB of the two designs, respectively, and 10dBm of output IP3 make them suitable for integrated in the low power transmitters. They consume 4.4mA and 6.3mA, respectively, when output is OdBm under 1.8V.
