Comments on “Analytical Design Equations for Class-E Power Amplifier”

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.
