This paper presents the design and experimental characterization of a portable high-precision single-phase lock-in instrument with phase adjustment. The core consists of an analog lock-in amplifier IC prototype, integrated in 0.18 µm CMOS technology with 1.8 V supply, which features programmable gain and operating frequency, resulting in a versatile on-chip solution with power consumption below 834 µW. It incorporates automatic phase alignment of the input and reference signals, performed through both a fixed −90° and a 4-bit digitally programmable phase shifter, specifically designed using commercially available components to operate at 1 kHz frequency. The system is driven by an Arduino YUN board, thus overall conforming a low-cost autonomous signal recovery instrument to determine, in real time, the electrical equivalent of resistive and capacitive sensors with a sensitivity of 16.3 µV/Ω @ εrS < 3% and 37 kV/F @ εrS < 5%, respectively.

Resumo -Histórias são relatos produzidos pelo homem a partir de seu olhar sobre situações vivenciadas na sociedade, escrevêlas exige um trabalho árduo e contínuo. Nessa perspectiva, compreender a História do Contestado entre os estados do Espírito Santo e Minas Gerais, com ênfase nas cidades de Barra de São Francisco -ES e Mantena-MG. O Contestado foi um período litigioso ocorrido na região norte das divisas entre Espírito Santo e Minas Gerais. Nos anos de 1937 a 1963, os dois Estados contestavam as ricas terras da região alegando erros de divisas territoriais. Diante do impasse, a violência, a desordem e o medo instalou-se região, que acabou ficando sob o controle das jurisdições mineiras e capixabas. Porém, em 1963, um acordo foi selado entre os dois Estados, com definição das divisas.Palavras-chave: Contestado. Barra de São Francisco. Mantena. História Oral. Gerais. In the years 1937 to 1963, the two states contested the rich lands of the region alleging errors of territorial currency. Faced with impasse, violence, disorder and fear, a region was installed, which ended up under the control of the mining and capixabas jurisdictions. However, in 1963, an agreement was sealed between the two states, with currency definition. Abstract -Stories are reports produced by man from his gaze on situations experienced in society, writing them requires a hard and continuous work. From this perspective, to understand the History of the Contestado between the states of Espírito Santo and Minas Gerais, with emphasis on the cities of Barra de São Francisco -ES and Mantena -MG, the scene of the greatest conflicts of the time. The Contestado was a litigious period occurred in the northern region of the border between Espírito Santo and Minas

“…Following this research line, in this work we have developed a new multi-channel data acquisition system with the following characteristics: open-hardware, open-software, easy to implement, and low-cost. The designed system is based on Arduino Due board, which is an open-source electronic prototyping platform of the most used in multiple disciplines in recent years (e.g., [33][34][35]).…”

Design and Implementation of an Arduino-Based Plug-and-Play Acquisition System for Seismic Noise Measurements

et al. 2019

The analysis of seismic noise provides a reliable estimation of the soil properties, which supposes the starting point for the assessment of the seismic hazard. The horizontal-to-vertical spectral ratio technique calculates the resonant frequency of the soil just by using a single three-component sensor. Array measurements require at least several vertical sensors registering simultaneously and their analysis provides an estimation of the surface waves dispersion curve. Although these methods are relatively cheaper than other geotechnical techniques, the cost of the sensors and the multi-channel data acquisition system means that small research groups cannot afford this kind of equipment. In this work, two prototypes for registering seismic noise have been developed and implemented: a three-channel acquisition system, optimized for working with three-component sensors; and a twelve-channel acquisition system, prepared for working simultaneously with twelve vertical geophones. Both prototypes are characterized by being open-hardware, open-software, easy to implement, and low-cost. The main aim is to provide a data acquisition system that can be reproduced and applied by any research group. Both developed prototypes have been tested and compared with other commercial equipment, showing their suitability to register seismic noise and to estimate the soil characteristics.
