Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

The chapter delves into the design and architecture of Delayed Switched Cascode Class-E Amplifiers and Doherty Power Amplifiers, highlighting the advantages of switched mode CMOS PAs for mm-Wave applications. It discusses the challenges and solutions associated with Class-E amplifiers, including the implementation of a cascode topology to minimize gate resistance and improve PAE. The chapter introduces a switched cascode Class-E PA with a tunable transmission line, offering a flexible and efficient design that can achieve higher PAE and lower switching losses. The implementation and measurement results demonstrate the effectiveness of the proposed design, showcasing an 8% improvement in PAE compared to conventional cascode topologies. This chapter is essential for engineers and researchers seeking to enhance the performance of power amplifiers in high-frequency applications.
