The capacitive-coupled and capacitive-feedback topology is adopted. The amplifier current consumption is $5.2 mu mathrm{A}$ or $18.2 mu mathrm{A}$ at 3 V supply for a mid-band gain of 39.4 dB or 25.9 dB, respectively. Each corner frequency is 2-bit programmable for amplifying biosignals located in different bands. The bandwidth can be extend from 0.15 Hz - 2.68 kHz to 0.03 Hz - 40.4 kHz. To avoid possible saturation at the differential output, a discharged switch is incorporated. The circuit has an input-referred noise of $2.99 mu text{Vrms}$ integrated from 0.1 Hz to 10 kHz. It was designed and simulated using $0.5 mu mathrm{m}$ 3M2P CMOS process. The circuit is in the manufacturing process.","PeriodicalId":278190,"journal":{"name":"2020 Argentine Conference on Electronics (CAE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127947364","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}

According to the requirements of the Water Cherenkov Detectors (WCD) used in LAGO, the new system must be capable of recording fast pulses (∼ns) from a photomultiplier (PMT), control the high voltage level applied to it, in addition to monitoring the atmospheric conditions in which the data were taken. Some figures of merit are shown, indicating the performance of the new system working with a WCD. The DAQ is based on a commercial board plus a custom-made interface board. This implementation includes scalers, sub-scalers, an automatic baseline correction algorithm, pressure & temperature sensing, geolocalization, an external trigger and the capability to set and monitor the high voltage applied to the PMT. The flexibility in the design of the system allows to adapt it to different particle detector technologies, such as silicon photomultipliers, resistive plate chambers and scintillators. Preliminary results prove the validity, reliability and high performance of the system.","PeriodicalId":278190,"journal":{"name":"2020 Argentine Conference on Electronics (CAE)","volume":"265 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132473884","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}

Parametric DC time dependent degradation is considered in all the devices of the circuit along with correlated flicker and thermal noise increase under hot carrier injection stress. Results show that, rather than the changes introduced by stress on DC parameters, the proposed topology is very sensitive to device level noise increase due to stress-induced traps, particularly at early stages of circuit life. This highlights the requirement of a unified simulation framework that takes into account not only DC/AC small signal degradation models but also device noise degradation in noise sensitive circuits.","PeriodicalId":278190,"journal":{"name":"2020 Argentine Conference on Electronics (CAE)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129032011","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}

For a fully digital design (i.e. A/D in the pixel), the digital circuit can consume a large portion of the available space depending on the process feature size, effective well capacity (absolute dynamic range), and in-pixel functionality. The upside is that the digital circuit scales with the process node. The down side is limiting available space for the analog (front end) portion of the pixel limiting the designs to CMOS processes with smaller feature size. As we previously reported on 55- and 65-nm designs, this paper shows results from two imagers fabricated on the 90-nm process. In addition to Random Telegraph Signal/Noise (RTS/N), this paper compares non-uniformity between the two designs with device mismatching being the main culprit.","PeriodicalId":278190,"journal":{"name":"2020 Argentine Conference on Electronics (CAE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115375248","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}

MOS dosimeters have been used for the last 50 years, and its performance has improved since then. To understand how a MOS dosimeter works its limitations and the different strategies to overcome them, it is important to overview the radiation effects in the MOS structure and how it can be used for dose estimation. Different reading methods are presented that improve some aspects of the performance of the MOS dosimeter, such as its lifespan or the temperature dependence of the dosimetric signal. Different well established MOS devices used for dosimetry are reviewed, pointing out its advantages and disadvantages. We finish with the description of some integrated circuits specially designed with the aim of outperform those MOS devices and incorporate more functionality to the dosimeter.","PeriodicalId":278190,"journal":{"name":"2020 Argentine Conference on Electronics (CAE)","volume":"258 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124032305","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 interference from other LTE users is particularly harmful due to the low power decay of the leakage in the frequency domain and the fact that LTE received signals might have higher power than that of NB-IoT. In this paper, we provide measurement results that validate the interference leakage predicted by simulations. Additionally, we propose a successive interference cancellation (SIC) algorithm that is able to remove the interference and is robust to differences between the power of the received signals.","PeriodicalId":278190,"journal":{"name":"2020 Argentine Conference on Electronics (CAE)","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129277024","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}
