We report a frequency-dependent output conductance of partially depleted SOI MOSFET's. For high-frequency analog applications, the output conductance is less than half and the dynamic range of V d is two times higher than the dc I I I-V V V characteristics would indicate. A simple physical model for the phenomenon that involves a phenomenological body charging capacitance and can fit data within 10% is presented.
