Abstract: This manuscript proposes a class-E power amplifier (CEPA), which drives an inductive-link for IoT applications. The proposed technique is a combination of Aquila optimiser (AO), pelican optimisation algorithm (POA). The catching-behaviour of AO is improvised with the help of the POA technique. Hence, it is named the Improved AO strategy. The proposed configuration resolves the trade-off between switch gate capacitance and ON resistance. A differential class-E PA with the inductor of split - slab is intended to satisfy the operational requirements set by the power amplifier. The performance of the proposed technique is validated in MATLAB site and it is compared with existing techniques.

Keywords: internet of things; class-E power amplifier; CEPA; inductive link; switch-on resistance WPT.
