Objective: The objective of this research was to design a 2.4 GHz class B 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. Methods: This paper introduces the design of a 2.4GHz class B power amplifier designed as dual gate topology. This class B power amplifier could transmit 26dBm output power to a 50Ω load. The power added efficiency was 60% minimum and the power gain was 90dB, the total power consumption was 6.9 mW. Results: Besides, accurate device modeling, is needed, due to the leakage and process variations. Conclusion : The performance of the power amplifier meets the specification requirements of the desired.
