CIRCUITS, DEVICES, METHODS AND COMBINATIONS RELATED TO SILICON-ON-INSULATOR BASED RADIO-FREQUENCY SWITCHES

摘要

Radio-frequency (RF) switch circuits are disclosed providing improved switching performance. An RF switch system typically includes a plurality of field- effect transistors (FETs) connected in series between first and second nodes, with each FET having a gate, a source, a drain and a body. Disclosed are, among others, various examples of circuits that couple different portions of a FET and/or different FETs to yield desirable performance improvements for RF switch systems. In some embodiments, one or more features of a given example can provide such performance improvements. In some embodiments, features from different examples can be combined to yield such performance improvements.
