Peregrine, GlobalFoundries debut next-generation RF SOI platform

January 26, 2017 // By Jean-Pierre Joosting

Peregrine Semiconductor has announced the UltraCMOS® 12, a next-generation RF SOI technology platform that boasts the industry’s lowest RONCOFF performance level of 80 fs—a 25-percent improvement over the last generation.

To develop the 300 mm UltraCMOS 12 platform, Peregrine collaborated with GlobalFoundries.


Peregrine Semiconductor’s next-generation platform, UltraCMOS® 12 technology, features an RONCOFF performance level of 80 fs.

A key metric for RF switching, RONCOFF is Peregrine’s performance benchmark for each new generation of the UltraCMOS platform. RONCOFF is a ratio of how much loss occurs when a radio signal goes through a switch in its ON state (RON, or on-resistance) and how much the radio signal leaks through the capacitor in its OFF state (COFF, or off capacitance). With each new UltraCMOS generation, Peregrine targets a 20-percent improvement in RONCOFF. UltraCMOS 12 technology surpasses this target and sets a new industry standard for RONCOFF performance.
