Abstract :
Silicon-on-sapphire (SOS) technology is gaining rapid ground in RF applications due to its inherent low parasitic capacitance and the availability of high Q passive components. In this paper, performance of different transistors in SOS technology for switching applications has been verified. Quality factor, OFF performance, and harmonic distortion of all N-types transistors have been simulated and a comparative analysis is provided. Based on this analysis it can be concluded that for the same W/L ratio, NL and IN transistors in the FC process give higher quality factor and also higher Con/Coff, while in the GC process, IN devices perform best.
