Design and Analysis of Tunnel FET for Low Power High Performance Applications

By Umesh Dutta M.K.Soni Manisha Pattanaik

DOI:, Pub. Date: 8 Jan. 2018

Tunnel FET is a promising device to replace MOSFET in low power high performance applications. This paper highlights and compares the best TFET designs proposed in the literature namely: Double gate Si-based TFET, InAs TFET device and III-V semiconductor (GaAs1-xSbx-InAs) based TFET device. Simulations are performed using TCAD tool and simulation results suggest that conventional DGTFET device has less on current and degraded subthreshold slope as compared to InAs and III-V semiconductor based TFET device. InAs based TFET device provides steep subthreshold slope of 61 mV/dec and off current of the order of nano-amperes at sub 1V operation thereby making it an ideal choice for low power high performance applications. The variation in the performance of the III-V HTFET device with the variation in the mole fraction is also studied in detail. Carefully choosing the mole fraction value in III-V semiconductor based HTFET device can lead to better device performance.

A Review of NBTI Degradation and its Impact on the Performance of SRAM

By Umesh Dutta M.K Soni Manisha Pattanaik

DOI:, Pub. Date: 8 Jun. 2016

Temporal degradation of VLSI design is a major reliability concern for highly scaled silicon IC technology. Negative Bias Temperature Instability (NBTI) in particular is a serious threat affecting the performance of both digital and analog circuits with time. This paper presents a review of NBTI degradation, its mechanism and various factors that affect the degradation caused by NBTI. Reaction Diffusion (RD) model based analytical expressions developed by various researchers are also discussed along with their features and underlying assumptions. Degradation in the Static RAM (SRAM) performance caused by NBTI is also discussed in detail along with the strategies that are employed to combat the effect of NBTI degradation in SRAM. Results of the review done for SRAM cell under NBTI degradation suggests that these design strategies are effective in improving the SRAM cell performance.
