Nettet21. aug. 2013 · A novel figure of merit (FOM) is proposed which allows absolute benchmarking of the carrier to noise ratio (CNR) of oscillators. Called Oscillator Design Efficiency (ODE), this FOM allows absolute comparison of designs. This is realized by comparison of a realized design with the best case (theoretical) oscillator design. NettetAlong with Johnson’s figure of merit, the additional considerations of doping, low field mobility, thermal constraints, and heterojunctions are discussed. The analysis is used to explain why gallium nitride-based high electron mobility transistors have become the material system of choice for high power high frequency applications.
