Multiobjective Genetic Algorithms Program for the Optimization of an OTA for Front-End Electronics

Abstract; The design of an interface to a specific sensor induces costs and design time mainly related to the analog part. So to reduce these costs, it should have been standardized like digital electronics. The aim of the present work is the elaboration of a method based on multiobjectives genetic algorithms (MOGAs) to allow automated […]

Investigation of interface, shallow and deep oxide traps under NBTI stress using charge pumping technique

Abstract; By extracting and eliminating the geometric component from the charge pumping current (ICP) in on-the-fly oxide trap method (OTFOT), we have been able to demonstrate that both interface (ΔNit) and deep hole oxide traps (ΔNotD) induced by the negative bias temperature instability (NBTI) are principally located in the lightly doped drain region (LDD region) […]

An Accurate Combination of on-the-fly Interface Trapand Threshold Voltage Methods for NBTI Degradation Extraction

Abstract; The Negative bias temperature instability (NBTI) is one of the most important reliability issues for modern CMOS technology. Accurate reliability prediction necessitates physically based models for NBTI and accurate methods for estimation of interface (∆N it ) and oxide trap (∆N ot ) generated under this degradation as well as mobility degradation (∆μ eff […]

On the Permanent Component profiling of the Negative Bias Temperature Instability in p-MOSFET Devices

Abstract; In this manuscript, we have investigated the negative bias temperature instability (NBTI) induced border-trap (Nbt) depth in the interfacial oxide region of PMOS transistors using multi-frequency charge pumping (MFCP) method. We emphasize on the distribution of the permanent component in the oxide near the interface, giving a clear insight on its effect on NBTI […]

Low magnetic field Impact on NBTI degradation

Abstract; This article presents the effect of low magnetic field (B < 10 mT) on both Negative Bias Temperature Instability (NBTI) stress and recovery. This effect is a study on commercial power double diffused MOS transistors (VDMOSFET). We show that the degradation is less important when the magnetic field is applied. The dynamic of the degradation change and […]

Deep Analysis of the Geometric Component in Charge Pumping of Polycrystalline Silicon Thin-Film Transistors

Abstract; In this paper, we model the geometric component in a charge pumping (CP) technique of polycrystalline silicon thin-film transistors (poly-Si TFTs). This model is based on both remaining carrier types when the device transits from accumulation to inversion and vice versa. Therefore, it depends on gate length (L) and width (W) as well as […]

Charge Pumping, Geometric Component, and Degradation Parameter Extraction in MOS Devices

Abstract; In this paper, we model the geometric component of a charge-pumping (CP) technique. Base on this proposed model, we have established an analytic equation for charge-pumping current. This equation seems to be a universal one since it is in agreement with CP experimental data of different technologies devices. Instead of the classical considerations regarding […]

On the Turn-around Phenomenon in N-MOS Transistors under NBTI Conditions

Abstract; We have experimentally analyzed negative bias temperature instability (NBTI) stress/recovery cycle on n-channel metal oxide semiconductor field effect transistors (n-MOSFET’s). Data obtained by current–voltage (I–V) and charge pumping (CP) techniques have revealed a turn-around phenomenon in both threshold voltage shift (ΔVth) and maximum CP current shift (ΔICP-Max). This allows us to separate the evolution of interface […]

On the Correlation between Circuit-level & Device-level Degradations due to AC NBTI Stress

Abstract; In this paper, an experimental analysis of the impact of dynamic negative bias temperature instability (NBTI) stress on the CMOS inverter dc response and temporal performance is presented. We analyzed the circuit behavior subjected to ac NBTI in the prospect to correlate the induced degradation with that seen at PMOS device level. The results […]

Experimental Investigation of NBTI Degradation in Power VDMOS Transistors Under Low Magnetic Field

Abstract; In this paper, we report an experimental evidence of the impact of applied a low magnetic field (B <; 10 mT) during negative bias temperature instability (NBTI) stress and recovery, on commercial power double diffused MOS transistor. We show that both interface (ANit) and oxide trap (ANot) induced by NBTI stress are reduced by […]
