A. Ortizconde et al., SERIES RESISTANCE AND EFFECTIVE CHANNEL-LENGTH EXTRACTION OF N-CHANNEL MOSFET AT 77-K, Electronics Letters, 30(8), 1994, pp. 670-672
A simple method is presented to extract the effective channel length a
nd series resistance of n-channel MOSFETs having 0.6-2.0 mum mask chan
nel lengths at room and liquid nitrogen temperatures. Our results show
that the effective channel length increases and the series resistance
decreases when the temperature is reduced from 300 to 77K.
