In this paper, a 13-bit successive approximation analog-to-digital converter (SAR ADC) with a conversion rate of 500-MS/s is introduced. The voltage domain interpolation (Interpolated) technique is used to achieve 4 bits per conversion, and the number of reduced comparators is reduced to half by using the time domain interpolation structure. The SAR ADC redundancy correction technique based on the pipelined ADC redundancy correction principle is investigated and discussed, allowing the ADC to have ± 0.5 LSB misalignment per conversion.","PeriodicalId":6693,"journal":{"name":"2021 6th International Conference on Integrated Circuits and Microsystems (ICICM)","volume":"23 1","pages":"65-68"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85254847","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}

System on chip (SoC) is a special IC chip with system architecture, generally including computing logic, acceleration logic, and peripheral units. It has the advantages of small size, low power consumption, and high flexibility, and has been widely used. In the SoC chip design process, logical timing is usually very tight, which will lead to great difficulties in the logic synthesis stage. In general, the conventional synthesis method will manually increase the proportion of path groups, low voltage threshold (LVT) cells, ultra-low voltage threshold (ULVT) cells to improve timing performance, but its timing closure is slow, which will prolong the whole SoC chip design cycle. In order to improve the convergence speed of the SoC chip logic synthesis, this paper proposes a progressive automatic logic synthesis (PALS) method, which adopts progressive form to add path groups, insert LVT and ULVT cells, and performs iteration automatically. In this method, the iterative optimization constraints have the advantages of gradual progression and comprehensive coverage, which improves the convergence speed of logic synthesis effectively. In addition, ARM CortexA7 is synthesized using PALS method, and the experimental results show that the timing convergence time of the PALS method proposed in this paper is reduced by 12% compared with the conventional method, proving the superiority of the PALS method.","PeriodicalId":6693,"journal":{"name":"2021 6th International Conference on Integrated Circuits and Microsystems (ICICM)","volume":"11 1","pages":"227-231"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90323454","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 simulation is mainly focused on the comparisons of heat transfer capability and characteristics for double-diamond heat dissipation structure and the others, including GaN on SiC, GaN on diamond and GaN on SiC with diamond spreader. Simulation demonstrates that the junction temperature of device with double-diamond structure is 120°C, significantly lower than that on SiC substrate, since the coordination of diamond substrate and diamond spreader strengthens heat dissipation in both directions. The results also show that the heat dissipation performance of device is improved about 15 % by adding only 10 $mu$m diamond spreader in double-diamond structure compared to that of single diamond substrate. In addition, the heat transfer ability could be further enhanced by optimizing the spreader thickness and the interface thermal resistance.","PeriodicalId":6693,"journal":{"name":"2021 6th International Conference on Integrated Circuits and Microsystems (ICICM)","volume":"2 1","pages":"55-60"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88577253","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}
