Abstract

This paper presents optimized Current-Mode Class-D (CMCD) RF Power Amplifiers (PA). The results demonstrate 73.63/79.75% Power Added Efficiency (PAE), for 29.5/26.5dBm output power in a standard 350/130nm CMOS technology at 2.4 GHz operation frequency for sine wave input. The proposed amplifier design is implemented using CADENCE tools (TSMC Foundry) and the simulation results are compared to the previous published work. Thank to intensive parameter optimization, the proposed design has succeeded in increasing the PAE.
