  This paper presents a complete closed-form analytical model for determining
the per-cycle energy consumption of stepwise adiabatic drivers used for driving
a capacitive load such as a power FET gate. The model takes into account the
number of steps used, the stepwise driver tank capacitance, the load
capacitance, and the stepwise driver switch resistance and on-time. Model
accuracy is compared to that of simulation and models from previous work.
