基于Gm/ID的MOSFET全范围阈值电压提取研究

On MOSFET Threshold Voltage Extraction Over the Full Range of Drain Voltage Based on Gm/ID

Nikolaos Makris, Matthias Bucher

摘要:

提出了一种覆盖从线性到饱和模式的整个漏源电压范围的MOSFET阈值电压提取方法。跨导电流比是从MOSFET的传输特性在低到高的漏极电压测量。基于基于电荷的建模方法,在整个漏极电压范围内获得了理想长沟道MOSFET的阈值电压的近似恒定值。该方法揭示了一个显着的增加的阈值电压与漏极电压的晕注入MOSFET在低漏极电压范围内。该方法受益于适度的反转操作,其中高场效应,如垂直场迁移率降低和串联电阻,是最小的。本方法适用于漏极电压的整个范围,是完全解析的,易于实现,并且与现有方法相比,提供了更一致的结果。

英文摘要:

A MOSFET threshold voltage extraction method covering the entire range of drain-to-source voltage, from linear to saturation modes, is presented. Transconductance-to-current ratio is obtained from MOSFET transfer characteristics measured at low to high drain voltage. Based on the charge-based modeling approach, a near-constant value of threshold voltage is obtained over the whole range of drain voltage for ideal, long-channel MOSFETs. The method reveals a distinct increase of threshold voltage versus drain voltage for halo-implanted MOSFETs in the low drain voltage range. The method benefits from moderate inversion operation, where high-field effects, such as vertical field mobility reduction and series resistances, are minimal. The present method is applicable over the full range of drain voltage, is fully analytical, easy to be implemented, and provides more consistent results when compared to existing methods.
