Abstract :
The output resistance (R/sub out/) most important device parameters for analog applications. However, it has been difficult to model R/sub out/ correctly. In this paper, we present a physical and accurate output resistance model that can be applied to both long-channel and submicrometer MOSFETs. Major short channel effects and hot-carrier effect, such as channel-length modulation (CLM), drain-induced-barrier-lowering (DIBL) and substrate current induced output resistance reduction, are all included in this model, and it is scalable with respect to different channel length L, gate oxide thickness T/sub ox/ and power supply V/sub dd/. This model can be incorporated into existing MOSFET´s model without introducing discontinuity.<>
