This TDC uses a bipolar transistor as the core device for temperature measurement and a second-order Sigma-Delta ADC to read the temperature information. In order to improve the accuracy, the PTAT bias circuit with finite current gain compensation resistor and Dynamic Element Matching (DEM) circuit with Bank-Swap structure is employed in the temperature front-end circuit, respectively. In the ADC design, Analog T- switches (AT-Switch) with complementary structures are employed to reduce the leakage current of MOS switches in a fully differential switched-capacitor integrator to improve the accuracy further. Implemented in TSMC 180nm CMOS, the TDC occupies 0.135mm2. The measurement results show that the average power consumption of the circuit is 95µW (@27°C) at a supply voltage of 1.8V. After temperature curve fitting, an inaccuracy of ±0.85°C(3σ) is achieved from -40°C to 85°C, which meets the requirements of the FBAR(Flim Bulk Acoustic-wave Resonator) oscillator for temperature compensation.","PeriodicalId":50387,"journal":{"name":"Ieice Electronics Express","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135560397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"An Enhanced Reconfigurable Dual-Clock FIFO for Inter-IP Data Transmission","authors":"Shugang Liu, Jiangtao Liu, Qiangguo Yu, Jie Zhan","doi":"10.1587/elex.20.20230354","DOIUrl":"https://doi.org/10.1587/elex.20.20230354","url":null,"abstract":"In integrated designs of multiple IP cores across clock domains, signal metastability can occur due to unequal wiring and variations in PVT. This leads to inconsistency between the signals obtained by the target and the signals at the source. Establishing a FIFO is one of the crucial methods for addressing data inconsistency. Therefore, this paper proposes a novel array structure based on one-hot coding, where the row and column codes generated by Johnson counters are XORed to create the address pointer. This innovation reduces the area for the FIFO and enables rapid control logic using one-hot coding. Furthermore, a state-based approach is employed to mitigate the impact of memory size on the empty/full detection circuit. It only records the read-and-write addresses, enhancing the reconfigurability of the FIFO. Using the SMIC 0.18µm process, the synthesis and simulation results demonstrate that the FIFO can achieve a maximum operating frequency of 830MHz. Additionally, compared to similar synchronous FIFO, it exhibits a significant 30% reduction in area. When considering different FIFO depths and widths, the method proposed in the paper shows an area reduction of 30% to 47% compared to similar synchronous methods. For a depth of 16 and a data width of one word, the power consumption is about 6.8 mW. The FIFO presented in this paper can serve as a reference for data transmission between different clock domains.","PeriodicalId":50387,"journal":{"name":"Ieice Electronics Express","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135596310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
