Webdesign. Commonly used varactors include the p-n junction varactors, PMOS varactors and accumulation mode (n or p-type) varactors. This paper discusses the results from the benchmarking of different two and three-terminal MOS varactor structures. The structures are first generated through process simulation based on the CMOS090 RF process WebThis type of diode has been used since 1980, in many applications such as bipolar VCO™s, FET VCO™s, Gunn VCO™s and tuneable filters. In most cases it has been possible to completely eliminate the use of linearizers, with resulting savings in size, weight, and cost, without giving up the traditional stability of thermal-oxide passi- ipg technology
