A Physical Model for Mosfet Output Resistance
نویسندگان
چکیده
The output resistance (hut) is one of the most important device parameters for analog applications. However, it has been difficult to model hut 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 (0 [l], drain-induced-barrier-lowering (DZBL) [2] [3] [4] and substrate current induced output resistance reduction [5] [6], are all included in this model, and it is scalable with respect to different channel length L , gate oxide thickness T, and power supply G d. This model can be incorporated into existing MOSFET's model without introducing discontinuity.

Output-Conductance Transition-Free Method for Improving Radio-Frequency Linearity of SOI MOSFET Circuits
In this article, a novel concept is introduced to improve the radio frequency (RF) linearity of partially-depleted (PD) silicon-on-insulator (SOI) MOSFET circuits. The transition due to the non-zero body resistance (RBody) in output conductance of PD SOI devices leads to linearity degradation. A relation for RBody is defined to eliminate the transition and a method to obtain transition-free c...
