From FPGA to ASIC implementation of an OpenRisc based SoC for VOIP Application

Abstract; SIC (Application Specific Integrated Circuit) design verification takes as long as the designers take to describe, synthesis and implement the design. The hybrid approach, where the design is first prototyped on an FPGA (Field-Programmable Gate Array) platform for functional validation and then implemented as an ASIC allows earlier defect detection in the design process […]

Compact UWB bandpass filter based on simple radial stub resonator structure

Abstract; In this letter, a new compact microstrip ultra‐wideband (UWB) bandpass filter (BPF) is proposed. Using a new electrical model leading to a simple structure based on radial stub resonator (RSR), its originality resides in its noteworthy simple design approach where the filter response can be accurately adjusted by tuning three parameters only. The fabricated […]

Compact ultra-wideband bandpass filter with notch band based on the impedance matching method

Abstract; In this work, a new ultra‐wideband (UWB) bandpass filter (BPF) with notch band (NB) at 5–6 GHz is presented. The design is performed using the impedance matching method based on optimization of objective function defined in the frequency range 3.1–10.6 GHz. The filter structure is composed of uniform transmission line loaded, at its center, […]

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 […]

Comparison of electrical performances of two n-in-p detectors with different implant type of guard ring by TCAD simulation

Abstract; This paper presents a preliminary comparative study for two different guard rings structures in the purpose of evaluating their electrical performances. The two structures are based on the n-in-p technology with different implant type of guard rings. I–V characteristics have been simulated using Silvaco/ATLAS software for both structures and compared for various parameters of […]
