A programmable gain is obtained varying both the common-mode current and the amplification time window. The design is verified through post-layout simulations for different PVT conditions. The amplifier achieves a configurable gain Av = 4 ± 15 % with a power consumption range {39–61} μW. For Av = 4, the input referred noise is σn = 93 μV while the distortion is negligible, resulting in an effective number of bits (ENOB) = 5.9 bits. The random offset due to fabrication process mismatches is σos = 5.8mV.","PeriodicalId":212534,"journal":{"name":"2023 Argentine Conference on Electronics (CAE)","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127459465","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 model includes the radiation-induced charge buildup within both the gate oxide of the standard transistors and the bird’s beak parasitic transistor due to LOCOS isolation method. The zero bias radiation response of standard MOSFETs is simulated, showing the difference between n- and p-channel transistors. For high dose levels, the charge buildup in the parasitic transistor leads to an increase of the off-state leakage current for nMOSFET. The radiation response of an inverter is shown as an example of the consequence this increment of the leakage current may cause to the simple CMOS circuit. The model showed to successfully predict the increment in the delay and the failure of the circuit for high absorbed doses.","PeriodicalId":212534,"journal":{"name":"2023 Argentine Conference on Electronics (CAE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129592713","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}

It is used in the industry for quality control in the production of photovoltaic devices, in scientific laboratories to characterize new materials, and in photovoltaic facilities to find module failures. The PM consists of applying a laser light beam perpendicularly on a photovoltaic device, scanning the surface point by point, and measuring the induced current as a function of the position of the beam. These systems require a high degree of mechanical stability, which leads to an increase in the characterization times when the area is large. In recent years, it has been made progress in the use of compressive sensing algorithms applied in PM tests in order to reduce moving parts and the measuring times. In this work we apply the compressive sensing technique to obtain a photocurrent map of Si photovoltaic devices. Results are compared with the ones obtained by the conventional technique.","PeriodicalId":212534,"journal":{"name":"2023 Argentine Conference on Electronics (CAE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132294059","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}

MIDNA output is a signal proportional to the amount of charge present in the floating gate node of the CCD and it is digitized by the acquisition system. An analysis of the noise produced by the signal-processing stages of the ASIC and their impact on the output noise is presented.

The field of computer vision has been increasingly employed for satellite imagery analysis to extract meaningful information from the data collected. However, the cost of launching and maintaining space-based missions can be prohibitive for certain applications, particularly those requiring low-cost testing. An alternative approach that has gained traction in recent years is the use of stratospheric balloons, which are capable of collecting data at high altitudes at a fraction of the cost and time required for space-based missions. This article presents a workflow for implementing a deep learning-based image classification system for stratospheric balloon imagery.
