Abstract

This chapter presents the first completely on-chip Doherty based Class-E PA in 22nm FDSOI. The PAs include a cascode topology for improved efficiency and a larger output power. To further improve the total PAE, the switching signal is applied to the input transistor of the Class-E PA as well as to the cascode transistor with a delay element that utilizes a tunable transmission line. The Doherty PA is preceded by an active balun that produces two 180^∘ out-of-phase signals followed by a variable gain amplifier (VGA). To the best of our knowledge this is the first Doherty design with switched cascode Class-E amplifier. Section 5.1 discusses the switched mode Class-E DPA Design and architecture. Section 5.2 presents the implementation and measurement results. Finally, Sect. 5.3 concludes the chapter.
