An annular nickel-zinc ferrite is used as the magnetic core of the HFCT, and the parameters such as the number of winding turns and the diameter of the enameled wire are optimized. To test the HFCT, an experimental test platform is built according to the technical specifications of high-frequency partial discharge charged detection equipment. The test contents of the HFCT include transmission impedance, sensitivity, anti-interference characteristics, etc. The test results show that the new HFCT has a good response performance from 1MHz to 25MHz, the maximum transmission impedance value can reach 16.4mV/mA, the apparent charge of 5pC can be measured and signal-to-noise ratio is greater than 2:1. In addition, the designed HFCT also has good anti-interference and stability. With the self-designed low-power portable high-voltage cable insulation tester (mainly including signal conditioning circuit and data acquisition circuit), in the high-voltage laboratory, built a simulated discharge experimental circuit on the plate-pin, ball-ball two discharge models for high-voltage testing, the use of the developed HFCT to detect the partial discharge of the insulating polyethylene medium. The test results show that the HFCT can detect the partial discharge pulse signals before breakdown, with accurate data and reliable performance.","PeriodicalId":50387,"journal":{"name":"Ieice Electronics Express","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135158806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data-aware coupled capacitors are employed to dynamically tune the driving ability of sensing transistors according to the data supposed to be read, thus improving the offset tolerance of sense amplifier (SA). Compared with the conventional current latch-type SA (CLSA), the simulation results in 55-nm CMOS technology show that the proposed scheme achieves more than 4.17X of the standard deviation of VOS (σOS) reduction across the range of supply voltage from 0.6V to 1.2V and reduce the read energy consumption and read delay to 54.9% and 45.5% respectively. Furthermore, the proposed scheme reduces the σOS by 2.19X compared to DIBBSA on average.","PeriodicalId":50387,"journal":{"name":"Ieice Electronics Express","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135710802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The parallel Two Section Transmission Line (TSTL) is introduced in the impedance matching network (IMN), generating adjustable TZs and compensating for the resulting unrelated difference of admittance at DB fundamentals, which enables the DB IMN exhibits adjustable TZs out-of-band. The matching bandwidth of the DB IMN is further analyzed to seek the target impedance for broadband DB matching. The series TSTL is employed to modulate the target impedance to the impedance of the drain at DB fundamentals while satisfying the high efficiency operating conditions at DB harmonics. For validation, a DB PA is designed and fabricated with a Cree CGH40010F GaN transistor. The fabricated DB PA features the saturated output power of 42.6 dBm and 42.0 dBm with the Power-Added Efficiency (PAE) of 66.1% and 67.8% at 0.9 GHz and 2.4 GHz, respectively. Specially, the bandwidth of the DB PA is 150 MHz, and two adjustable TZs are shown out-of-band.","PeriodicalId":50387,"journal":{"name":"Ieice Electronics Express","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135953558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
