The comparison is performed to provide a power-efficient rectifier for RF energy harvesting at 915 MHz. The I-V characteristics of a conventional MOS diode and an ultra-low power diode (ULPD) are compared in terms of their leakage current. It is observed in the simulation of a 2-stage RF rectifier that minimizing the leakage current using ULPD improves the power conversion efficiency (PCE) of the RF rectifier. Both rectifiers also utilize back gate polarization (BGP) to boost the output voltages. ULPD achieved a Max PCE of 52 %, whereas conventional MOS diode achieved Max PCE of 47 % at 0dBm input power.","PeriodicalId":198335,"journal":{"name":"2022 20th IEEE Interregional NEWCAS Conference (NEWCAS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130125915","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 OTA consists of two amplifying stages and a feed forward compensating path designed to provide a high differential gain while suppressing the common-mode input signal, thereby providing a high common-mode rejection ratio (CMRR). In this OTA, the entire transistors are biased in subthreshold region to allow for an ultra-low power consumption. According to the open loop simulation results, the circuit provides a low-frequency gain of 61 dB, CMRR of 110 dB, power supply rejection ratio (PSRR) of 69.6 dB, and phase margin of 57° for a 1-pF differential load capacitor. Using a capacitive feedback, the closed loop gain is set to 37.8 dB, and the 3-dB bandwidth is 8.33 kHz. The input-referred noise integrated from 250 Hz to 10 kHz is 4.2 μVrms, while the circuit draws only 420 nA from a 0.3 V supply, corresponding to a noise efficiency factor (NEF) of 1.17.

A low temperature co-fired ceramic (LTCC) based interposer providing mechanical strength between the two substrates and electrical isolation is used. The gate driver die integrated inside the module is a non-isolated single-channel driver with a variable drive strength control feature that can safely operate up to 175ºC. Giant magnetoresistance (GMR) based current measurement solution is implemented, which is contactless and can measure both AC and DC current. A multi-layer LTCC or printed circuit board (PCB) based AC power terminal is proposed to integrate the GMR sensor into the module.

The model’s performance was proved using a dataset of 8566 corrosion and fatigue acoustic emission signals. To identify corrosion and fatigue acoustic emission signals, the model attained a 99.7 percent accuracy, demonstrating the efficacy of the suggested model for real-time reliability.
