Effects of the gate voltages on threshold (Vth), transconductance (gm), breakdown voltage (VBR), cutoff frequency (fT), maximum frequency of oscillation (fmax) and minimum noise figure (NFmin) are systematically investigated with different gate structures (π–Shaped p-GaN MISHEMT, π–Shaped p-GaN HEMT, π–Gate HEMT). A comparative study demonstrates that π–Gate with additional p-GaN and insulating layer makes the device effectively operate in the enhancement mode having a threshold voltage (Vth) = 1.72 V with a breakdown voltage (VBR) = 341 V, exhibiting better gate control with maximum transconductance (gm,max) of 0.321 S/mm. In addition, the proposed device architecture with an optimized gate structure maintains a balance between a positive device threshold and a high breakdown voltage and achieves a better noise immunity with the minimum noise figure of 0.64 dB while operating at 10 GHz with a cutoff frequency (fT) of 33.4 GHz, and a maximum stable operating frequency (fmax) of 82.3 GHz. Moreover, the device achieved an outstanding Vth, gm,max, VBR, fT, fmax and NFmin making it suitable for high-power, high-speed electronics, and low-noise amplifiers.","PeriodicalId":35778,"journal":{"name":"International Journal of High Speed Electronics and Systems","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49277005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This PRBS generator design is based on Linear Feedback Shift Registers (LFSR) and optical XOR and AND gates. The optical logical gates are based on quantum dot-semiconductor optical amplifier Mach-Zehnder interferometer (QD-SOA-MZI). With two photon absorption (TPA) in quantum dot-semiconductor optical amplifier (QD-SOA), this kind of optical logic gates performs well when processing data in an ultra-fast timescale and therefore able to function as high speed PRBS generator. Result shows that it’s possible for this scheme to realize all-optical encryption and decryption at high process rate up to 320 Gb/s. We simulated different ways of generating keystream with schemes such as cascaded generator, parallel generator and alternating step generator. These generators use more than one LFSR.

Two prototype variants were fabricated, incorporating FeCo sputtered films of different thicknesses on 4 μm polyimide jacket single mode fiber. The sensors were incorporated into a fiber optic interferometric measurement apparatus to characterize time-varying magnetic field sensitivity. Device results are presented which demonstrate sensitivity is a function of film thickness.

The adequate utilization and operation of the battery are improved in the flexibility range by the permutation of the battery and the ultracapacitor in the electric vehicle. The overall system performance is determined by the energy management system which plays a significant part in dual-energy storage systems. The major intent of this research is to enhance the performance of electric vehicles which is achieved by maintaining the charge of depleting and charge of sustaining level in the battery and the state of charge in the ultracapacitor. The proposed method controls the state of charge of the battery and the ultracapacitor to make sure the availability of charge throughout the complete settling rate of the battery in the electric vehicle. To attain this condition, the dual converter-based two-stage Artificial Neural Network is initialized. In the first stage of the Artificial Neural Network, the charge sustained in the ultracapacitor is controlled during acceleration which completely depends on the velocity of the vehicles. In contrast to that, in the second stage of the Artificial Neural Network, charge depleting in the UC is trained by connectionless with varying vehicle velocities at deceleration rates. The production and investigation of parameters are not effectively optimized using conventional methods hence the herding and howling characters are combined together and proposed energetic and problem-solving optimization-based metaheuristic algorithm that efficiently tunes the parameters. The SOC rate of the battery for three driving cycles using the proposed method follows FTP75 71.309% at 2474th s and J1015 attained 90.840% at 660th s and the UDDS attained 81.647%. The SOC rate of the Ultracapacitor for three driving cycles using the proposed method follows FTP75 63.518% at 2474 s, J1015 attained 69.332% at 660 s and UDDs attained 67.049%. The experimental arrangement is executed in MATLAB-Simulink. The state of charge of the battery and the ultracapacitors for the varying drive cycles as FTP75, J1015, and UDDS are experimentally validated and verified with the prevailing methods. The developed method reveals better performance for enhancing the lifespan of the power storeroom system in electric vehicles.","PeriodicalId":35778,"journal":{"name":"International Journal of High Speed Electronics and Systems","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46052239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
