Abstract—The objective of this research was to design a 2.4 GHz class AB Power Amplifier (PA), with 0.18um Semiconductor Manufacturing International Corporation (SMIC) CMOS technology by using Cadence software, for health care applications. The ultimate goal for such application is to minimize the trade-offs between performance and cost, and between performance and low power consumption design. This power amplifier can transmit 8.5 dBm output power to a 50Ω load. The power added efficiency is 8.2% at 1dB compression point and the power gain is 10dB, the total power consumption is 0.15W. The performance of the power amplifier meets the specification requirements of the desired.

Index Terms—two stage, class AB, power amplifier
