A Novel Design Method for Compact UWB Bandpass Filters

Abstract; In this letter, a new design method of ultra wideband bandpass filter (UWB BPF) is proposed. Based on a symmetrical structure of a simple uniform line loaded by a stepped-impedance open stub (SIS) connected at its center, the proposed design method employs simultaneously the optimization of a defined objective function in the range of […]

Efficient UWB filter design technique for integrated passive device implementation

Abstract; A new approach is proposed to act as an efficient design technique for the implementation of ultra-wideband (UWB) bandpass filters in integrated passive device technology. The proposed design is based on two major original contributions. First, the use of hourglass filter theory which, to the best of authors knowledge, has not been applied yet […]

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 […]

FEM Modeling of Sensitive Layer Swelling Effect on Microbalance Gas Sensor Based on TFBAR Resonator

Abstract; The electromechanical response of a chemical gas sensor based on a TFBAR (Thin Film Bulk Acoustic Resonator) structure coated with a sensitive polymer layer was simulated with a FEM (Finite Elements Method) software (COMSOL Multiphysics®). The principle of sensing is based on the change of the mechanical properties of the polymer due to the […]
