The mathematical approximate calculation is used to optimize the circuit structure of the rotating module in the excess-four algorithm, which reduces the adder in the rotating module and the hardware consumption of the circuit effectively. By removing the carry-over operation of the phase accumulating module, all the three-level rotating modules have the same structure, which ensures the same delay in all rotating units. The approach makes more advantages in the design of high-speed DDS circuits. Using the improved rotating structure, this paper implements the design of a highspeed DDS digital unit up to 6Gsps, with the SFDR above 88dBc, up to 104dBc. The single DDS core area is approximately 0.14 mm2 and the power consumption is 0.01mW/ MHz, using the Synopsys' SMIC 65nm process library tool to complete ASIC back-end design. In the case of SFDR that meets most of the high-speed DDS digital parts, the area and power consumption in this paper are greatly improved, compared with the conventional implementation method.","PeriodicalId":319342,"journal":{"name":"2019 IEEE 13th International Conference on ASIC (ASICON)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133631818","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}

As a key step in the design flow, multiple patterning layout decomposition (MPLD) is critical to design closure. Due to the $mathcal{NP}$-hardness of the general decomposition problem, various efficient algorithms have been proposed with high quality solutions. However, with increasingly complicated design flow and peripheral processing steps, developing a high-quality layout decomposer becomes more and more difficult, slowing down the further advancement in this field. This paper presents OpenMPL [1], an open-source layout decomposition framework, with well-separated peripheral processing and the core solving steps. We demonstrate the flexibility of the framework with efficient implementations of various state-of-the-art algorithms, which enable us to reproduce most of the recent results on widely-recognized benchmarks. We believe OpenMPL can pave the road for developing layout decomposition engines and stimulate further researches on this problem.","PeriodicalId":319342,"journal":{"name":"2019 IEEE 13th International Conference on ASIC (ASICON)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115393070","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 proposed structure significantly suppresses the quantization noise (QN) by employing a high-resolution quantizer with a segmented MSB/LSB DAC feedback in the first loop as well as noise coupling techniques in both loops. Reducing QN of the first loop significantly decreases the output swings of the integrators, thus improving the stability of the first loop. Besides, the construction of one extra order shaping function mitigates the leakage of coarse QN introduced by a gain mismatch between MSB and LSB DACs of the high-resolution quantizer. Simulation results demonstrate the effectiveness of the proposed architecture to achieve high resolution while employing low-gain op-amps for all integrators.","PeriodicalId":319342,"journal":{"name":"2019 IEEE 13th International Conference on ASIC (ASICON)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124251043","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}

Instead of adopting operational amplifiers for voltage-to-current conversion in conventional methods, an adaptive compensation mechanism is presented to realize a current linearly proportional to regulated output voltage, Vo, with no operational amplifier, which is used to obtain a voltage proportional to output voltage. Besides, a resistor-capacitor filter is utilized to achieve a ramp signal with slope proportional to supply voltage, VIN. By this method, an on time, TON, proportional to Vo/VIN is realized, which is the core control law of AOT Buck converters. The proposed circuit is validated in a 0.18μm BCD technology, which demonstrates the accuracy of the TON is higher than 86% with temperatures and process variations. In the case of VIN=5V and Vo=1.2V, the average dynamic current of the proposed on-time generator is only 1.465μA in one switching period Tsw, while consuming zero quiescent power.","PeriodicalId":319342,"journal":{"name":"2019 IEEE 13th International Conference on ASIC (ASICON)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124323857","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 12-bit single-slope ADC (SS-ADC), employing the proposed ramp generator, has been implemented in a 0.11-µm CMOS process. The simulation results show that the offset of the ramp's stop voltage is reduced to 0.1 LSB and the nonlinearity of the ramp is 0.034%.

Lowering operation voltage is an effective way to reduce power. As the overdrive voltage, Vg-Vth, becomes smaller, the device is more vulnerable to threshold voltage jitters. One source for the jitter is Random Telegraph Noises (RTN), which cause a fluctuation in both drain current, ΔId, and threshold voltage, ΔVth. Early works on RTN were focused on measuring ΔId and then evaluate ΔVth from ΔId/gm, where gm is transconductance. The accuracy of ΔVth obtained in this way is not known. The objective of this work is to assess its accuracy by comparing it with the ΔVth directly measured from pulse Id-Vg. It will be shown that the correlation between these two is poor, so that ΔVth must not be evaluated from ΔId/gm. This is caused by the device-specific localized current distribution near the threshold.","PeriodicalId":319342,"journal":{"name":"2019 IEEE 13th International Conference on ASIC (ASICON)","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117140247","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}
