Spectre RF Option
Spectre RF technology, an option to the Spectre Circuit Simulation Platform from Cadence, provides RF analyses for the design and verification of RFIC and MMIC designs such as mixers, transceivers, power amplifiers, and high-speed analog designs, including dividers, switched capacitors, filters, and phased-lock loops (PLLs). Spectre RF Option was first released in 1996 and was notable for three reasons: It was arguably the first RF simulator as it was the first to be designed for large bipolar and CMOS RF circuits; it used shooting methods as its base algorithm; and it pioneered the use of Krylov subspace methods.
