Abstract :
S-SEED switching operation is studied, and an analysis technique introduced that produces a closed form expression relating the switching voltage to the input power contrast ratio and the responsivity characteristics of the device. A closed form equation for the switching time, and a general switching condition are derived as well. The analysis technique uses a single slope linear approximation to the responsivity curve, and is readily extended to a three epoch approach as well as an N-segment analysis scheme. Theoretical analysis is verified with a computer simulation using experimental data. A comprehensive model of the S-SEED with series and parallel resistors was also studied. It was found that the switching time could be reduced by as much as 24% over the purely capacitive model, and switching achieved with a minimum power ratio
