In this work, we provide a device-circuit-algorithm simulation framework and propose the corresponding design guidelines. The simulation framework supports both inference and on-chip training, and a physics-based device model for analog RRAM is embedded to the framework to benchmark the CIM system. Nonideal effects and reliability issues of analog RRAM device are fully considered. Besides, array IR-drop and peripheral circuit are also modeled. Based on the evaluation results, optimization guidelines to suppress the impact of device nonidealities, reliability degradation and array IR-drop are proposed. This work provides a useful end-to-end co-design tool for developing large-scale computation-in-memory systems.","PeriodicalId":6737,"journal":{"name":"2021 International Conference on IC Design and Technology (ICICDT)","volume":"58 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75075085","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 method performs proper and effective sorting and reconstruction of the unit capacitors in the capacitor array before the SAR ADC performs data conversion. In addition, an achievable digital bubble sorting module is proposed to be used in this sorting scheme, which overcomes the limitation that the analog bubble sorting module cannot be applied to high-precision SAR ADC due to the complexity of the analog bubble sorting module. For the C-DAC using N unit capacitors, a digital bubble sorting circuit is used instead of an analog bubble sorting circuit, which can reduce the number of digital-to-analog connection signal lines from N2 to N. A 1 MS/s 8-bit SAR ADC is designed based on XFAB 0.18 μm process to verify this method. The results show that before and after calibration, SNDR is increased by 3.6 dB, SFDR is increased by 11.9 dB, and ENOB can reach 7.9. The method is simple and reliable, and is suitable for various SAR ADCs based on charge redistribution structures.","PeriodicalId":6737,"journal":{"name":"2021 International Conference on IC Design and Technology (ICICDT)","volume":"10 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90660400","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 semi-enclosed structure allows the tuning of the characteristic impedance. 3D electromagnetic simulations give results of 1.8 dB/mm insertion loss and a reflection coefficient of −28 dB at 60 GHz, for a 50-ohm matched design.
