摘要

Threshold voltage (V_(TH)) is the most evocative aspect of MOSFET operation. It is the crucial device constraint to model on-off transition characteristics. Precise V_(TH) value of the device is extracted and evaluated by several estimation techniques. However, these assessed values of V_(TH) diverge from the exact values due to various short channel effects (SCEs) and non-idealities present in the device. Numerous prevalent V_(TH) extraction methods are discussed. All the results are verified by extensive 2-D TCAD simulation and confirmed through analytical results at 10-nm technology node. Aim of this research paper is to explore and present a comparative study of largely applied threshold extraction methods for bulk driven nano-MOSFETs especially at 10-nm technology node along with various sub 45-nm technology nodes. Application of the threshold extraction methods to implement noise analysis is briefly presented to infer the most appropriate extraction method at nanometer technology nodes.
