While different functions have been used to represent loop gain, generally these functions yield similar phase margins so that the designer is usually not concerned with the particular function used. A development and comparison of two main approaches to finding loop gain, one focusing on a controlled source, Bode’s Return Ratio, the other keeping circuit variables foremost, the driving point impedance approach, leading to different ‘loop gain’ representations is presented. The source of this difference is found, concluding that the approach using a circuit focus analysis produces consistent results for phase margin while the Return Ratio may not making the former the preferred method.","PeriodicalId":287815,"journal":{"name":"2019 IEEE 62nd International Midwest Symposium on Circuits and Systems (MWSCAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128765470","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}

In order to improve the efficiency of this time-consuming method, a new calibration procedure is proposed. It allows to reduce the calibration effort associated with fingerprinting considerably and ensures a sufficient accuracy at the same time. The proposed procedure takes into account the geometry of the environment subject to study, in order to empirically estimate the distribution of the signal strength at predefined positions. Thus, mobile sensor localization can be carried out robustly and the deviation from real position is less than 0.75 m in about 90% of the cases. This is achieved even though the calibration effort is reduced by almost 84% compared to the original one.","PeriodicalId":287815,"journal":{"name":"2019 IEEE 62nd International Midwest Symposium on Circuits and Systems (MWSCAS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122253543","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 circuit is called a variable fast transient digitizer (VFTD). This paper provides an overview of the design and measured test results. The VFTD is designed to sample a high-speed analog input signal and later reconstruct the captured signal at a much slower rate, for example, around three orders of magnitude. This approach eliminates quantization error in the captured signal. Further, this approach enables the use of slow, low cost, analog-to-digital converters such as those found in microcontrollers. The VFTD discussed in this paper uses 256 sequential sample and hold cells with a process dependent variable delay element controlled by an off-chip voltage source. Using a power supply voltage of 5V the input range extends from 0 V to 3 V corresponding to an output voltage range from 2 V to 5 V, a capture window range from 81 ns to 1.78 µs, and a sampling rate range from 143.82 MS/s to 3.16 GS/s.

A Novel Design Gate based Low-Cost Configurable RO PUF using Reversible Logic 一种基于可逆逻辑的低成本可配置RO PUF设计

Bayoumi","doi":"10.1109/MWSCAS.2019.8885015","DOIUrl":"https://doi.org/10.1109/MWSCAS.2019.8885015","url":null,"abstract":"A Physical Unclonable Function (PUF) is a one-to-one (1:1) or a one-to-many(1:M) functional mapping operation. Given an input, which is termed as a Challenge, a PUF function produces response(s), which is termed as Response. Therefore, any PUF can be mathematically defined with its unique CRP behavior. Silicon PUFs can be implemented mainly for hardware security and thus to guarantee IP-protection. On the other side of the discussion, we are standing at the beginning of the quantum computation era, where we may start replacing all classical digital logics with the reversible logic ones. In conventional circuits, during any digital logic operation, we generally loose bits of input information (fan-in) at the output end (fan-out) and which results in unavoidable dissipation of a significant amount of energy. In reversible logic operation, we can preserve any inputoutput information bits at the input as well as output end and thus this technology can be implemented to minimize significant heat dissipation and power consumption for a fully functional physical chip while increasing the speed. The only trade-off will be designing complexity and wafer area which is our future research focus. In this paper, we propose the reversible logic design for an existing XOR Gate based Low-Cost Congurable RO PUF structure based on Feynman gate as a reversible logic block. A comparative analysis between classical and quantum logic function is also given on various parameters along with limitations of conventional computing. The proposed approach is implemented using VHDL on Xilinx-7 FPGA.","PeriodicalId":287815,"journal":{"name":"2019 IEEE 62nd International Midwest Symposium on Circuits and Systems (MWSCAS)","volume":"81 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133007578","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}
