It consists of four Negative Charge Pump (NCP) stages and a 4-phase non-overlapping Clock Generator (CG), where the 4 NCP stages are configurable by external digital signals. This generates a wide output voltage range necessary to control different SWF modes, such as opaque, transparent, and tinted modes. TSMC 0.18- m HV BCD (High-Voltage Bipolar-CMOS-DMOS) process was used to fabricate the proposed negative voltage generator on silicon. Measurement results demonstrate that at switching frequency (fsw) = 20 MHz, supplied voltage (VDD) = 4.5 V and Vin = GND, it generates a wide output voltage range of −3.9 to −14.0 V, achieving the widest voltage range among the prior works, which covers the required negative voltage range for SWF usage. The peak efficiency is measured on silicon to be 58.08% .","PeriodicalId":13968,"journal":{"name":"International Journal of Electronics Letters","volume":"11 1","pages":"361 - 379"},"PeriodicalIF":0.0,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46035033","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}

In this approach, the wideband is split into non-overlapping multiple subbands to determine the vacant subbands. The proposed detection scheme does not require apriori knowledge about the primary users or the noise signals and has lesser computational complexity. Simulation results show better probability of detection for the proposed method in comparison with the existing methods.","PeriodicalId":13968,"journal":{"name":"International Journal of Electronics Letters","volume":"11 1","pages":"355 - 360"},"PeriodicalIF":0.0,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45711266","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}

The NADGNFET in 90 nm device length is the proposal of this work to improve the second-order effects as well transistor non-linear performance at radio frequency (RF). A non-aligned device in this work consists of two gates extending to the source and drain region with 44.44% channel overlap in total device length. As compared to a full overlap device, the present device has shown better results in Analog Figure of Merit (FOM) and RF parameters like: ION current, ION/IOFF ratio, DIBL (Drain Induced Barrier lowering), SS (Subthreshold Swing), Intrinsic gain (AVO), Transconductance Generation Factor (TGF), Transconductance Frequency Product (TFP), Cut-off frequency (fT), Intercepted Input Power-3 (IIP3) and Intermodulation Distortion power-3 (IMD3). The use of dielectric material with high dielectric constant (HfO2, k = 24) in gate oxide reduces DIBL by 50%, increases the ION/IOFF ratio by 59.1%, increases the Intrinsic gain by 50% compared to low-k dielectric constant (SiO2, k = 3.9). However, results also shows that high-frequency parameters’ results were better with low-k dielectric constant. This gives a trade-off in device application.","PeriodicalId":13968,"journal":{"name":"International Journal of Electronics Letters","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42667447","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}
