This paper presents a novel platform for the efficient analysis, design, and optimization of ideal single-ended Class-E power amplifiers (PAs). It employs a comprehensive time-domain analytical model, which extends the conventional design space by incorporating variable duty cycles, variable voltage switching (VVS), and variable derivative voltage switching (VDS), enabling precise evaluation of key performance parameters such as harmonic efficiency, maximum output power capability, maximum operating frequency, and device stress. To facilitate practical design verification, an open-source, GUI-based CAD tool has been developed, providing researchers with an accessible and interactive environment for analysis and validation. In addition, a Python-based global optimization algorithm is integrated into the framework to automate component selection and enhance design robustness, particularly in scenarios involving finite DC-feed inductance. The accuracy and applicability of the proposed methodology are validated through nonlinear harmonic balance (HB) simulations. The results confirm the model’s ability to predict system behavior with high fidelity, making it a valuable resource for both academic and industrial design applications.

In their seminal work, Acar et al. (2007) proposed analytical design equations for Class E power amplifiers, which have significantly influenced subsequent research in this field. However, their analysis contains calculation errors in the evaluation of certain expressions, leading to inaccuracies in the derived design equations. This error results in significantly incorrect values for the design parameters, which, in turn, affect the accuracy of the overall design set. This work addresses these errors, providing a corrected set of design equations for Class E PAs, further supported by supplementary Python code, enabling researchers to readily explore and verify the corrected Class E design framework.
