J. Victory et al., A 4-TERMINAL COMPACT MODEL FOR HIGH-VOLTAGE DIFFUSED RESISTORS WITH FIELD PLATES, IEEE journal of solid-state circuits, 33(9), 1998, pp. 1453-1458
This paper presents a four-terminal, physically based, high-voltage di
ffused resistor model, The model accounts for depletion, inversion, an
d accumulation at the surface due to the MOS effect of metal field pla
tes, as well as the depletion pinching effect at the sides and bottom
of the diffused resistor.
