This paper aims to explore and compare the dependence of power amplifier performance parameters on the loaded quality factor of the resonant circuit, the technology node used and the operating frequency for different variants of the class E power amplifier. In spite of the fact that the circuit parameter variations of the basic class E amplifier are present in the literature, there is a lack of comparative analysis with respect to other class E power amplifiers based on diverse tuned load networks. Moreover, the effects of these three parameters are rarely discussed. The comparative analysis helps the designers to narrow down the selection of a power amplifier to be used for a particular application. This study is focused on the use of class E power amplifiers in biomedical implants at the Medical Implant Communication Service band and Industrial Scientific and Medical band. It is observed that the power added efficiency and the power gain have an inverse dependence on the loaded quality factor, frequency and the technology node while the output power depends directly on these parameters.

负载品质因数、技术节点和工作频率对各种E类功放拓扑影响的对比分析

本文旨在探索和比较功率放大器性能参数对谐振电路的负载品质因数、使用的技术节点和 E 类功率放大器的不同变体的工作频率的依赖性。尽管文献中存在基本 E 类放大器的电路参数变化，但缺乏与基于不同调谐负载网络的其他 E 类功率放大器的比较分析。此外，很少讨论这三个参数的影响。比较分析有助于设计人员缩小用于特定应用的功率放大器的选择范围。本研究的重点是在医疗植入物通信服务频段和工业科学与医疗频段的生物医学植入物中使用 E 类功率放大器。可以观察到，功率附加效率和功率增益与负载品质因数、频率和技术节点成反比，而输出功率直接取决于这些参数。
