The parallel data acquisition from multiple sensors is commonly used in Sonar based systems to increase distance measurement accuracy and reliability. Due to the mismatch in the analog path and PVT variations, the sensor signal experience delay among multiple channels. It causes phase difference which need to be consider for precise distance measurement. A LabVIEW based real time phase difference measurement method is proposed by using NI PXIe-6555 high speed digital I/O (HSDIO). The serial digital data from sensor’s ADC is converted into parallel in FPGA and then multiplexed with channel ID. The NI PXIe-6555 reads parallel multiplexed data from FPGA and calculate phase difference among multiple channels in LabVIEW with six digit fractional precision. A real time phase difference measurement of two parallel channel ADC chip for SONAR application is also performed while considering channel mismatch and PVT variations.","PeriodicalId":113802,"journal":{"name":"2019 International SoC Design Conference (ISOCC)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116258298","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}

A multi-phase MDLL is utilized to provide the 8- phase reference clocks needed for the PI-based CDR, thereby achieving the power reduction effect. A near-ground signaling (NGS) receiver with a passive CTLE is used for lower power operation at 20 Gbps/channel.

In an ideal case, the PLL jitter and power should be mostly determined by the VCO and Ref, while the other components like PD, CP, LF and divider adds negligible noise and consumes negligible power.

By shifting the corresponding signals of the faulty TSVs vertically and diagonally to the non-faulty TSVs, the proposed method maintains repair rate of TSV to 88.6% when there are 8 faulty TSVs.

By re-purposing the peripheral circuits, the certain NVM array can perform both storage and computing operations to accelerate the data-intensive convention Neural Networks (CNNs). However, the parallelism of the NVM-based CIM should be considered. In this paper, we present a CIM architecture developed by the Spin-orbit Torque (SOT) MRAM using both read-out and write-in operations. We highlight the memory structure and control method of the write-in operations. With the excellent write performance of SOT-MRAM, the proposed writein operation can obtain ultra-fast and energy-efficient computing data operations.
