For mixed mode applications, the analog engineer must cope with these issues to design analog-to-digital converters or analog applications using nanometric CMOS devices. In this paper, a design approach based on a multiple input floating gate technology is applied to a fully differential low power, low voltage operational transconductance amplifier that allows the use of low supply voltages and reduces the mismatch of the transistors. Simulation results indicate that the use of the floating gate approach does not show any advantage to control the gain of the amplifier. However, this approach is very useful as a means to control the differential pair voltage of the proposed design, allowing an offset voltage compensation of nearly zero volts. The performance of the proposed design approach is demonstrated by considering a voltage supply bias of +/− 0.45V, by obtaining a dissipated power of 12.2 microwatts, a bandwidth of 120 kHz, and 35 dB gain. The design is performed using the Cadence design framework environment based on a 130nm technology.","PeriodicalId":260469,"journal":{"name":"2017 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123298009","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}

Photoplethysmography (PPG) has been used to determine beat-to-beat blood volume changes in both arterial and surrounding tissues. In this work we used a characteristic of the pulsatile signal, mainly associated with the changes in the arterial diameters, the amplitude of the photoplethysmographic beat to beat pulse (PPGAV) and its corresponding association with the modification of the ANS activity. In this study participated a group of thirty volunteers (15M, 15F, 22.9±1.95 years). In order to stimulate the ANS we used the five minutes clinostatism to orthostatism maneuver by which we obtained the tachograms and the amplitudes of the PPG pulses. Later the frequency domain analysis was carried out by Statistica Software, determining the high and low frequency components for both maneuvers. To establish the linear relationship in the frequency domain, the spectral coherence function was used. The analysis of HRV and PPGAV in this group of volunteers revealed that there is a decrease in the PPG amplitude at the clinostatism / orthostatism postural change, suggesting an increase of the sympathetic activity towards the blood vessels, which causes vasoconstriction, thus reflecting a decrease in the value of the spectral coherence in response to the stimulus caused by the maneuver.","PeriodicalId":260469,"journal":{"name":"2017 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128573602","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 inverter uses Sinusoidal Pulse Width Modulation (SPWM) as the most common method for inverter controlling due to presents some advantages to other modulation techniques as, output voltage harmonic content reduction, the power loss in the switching devices is low and can be easily implemented using a digital controller. However, the SPWM technique can be improved by mean of the own concepts, thus a simple and practical implementation can be achieved. In this paper, a simple and effective methodology for switching time calculation for a SPWM three phase inverter is presented. A detailed methodology and algorithm are provided to program three independent microcontrollers, one for each phase, which must be synchronized to produce the right modulation. Therefore, the three phases are handled independently, and each phase can be controlled in a decoupled mode. In addition, the programming can be carried out in any programming software for simple and known functions, in this case MATLAB is used. In order to assess the proposed methodology and corroborate the inverter proper behavior, the microcontrollers simulation with the calculated switching times in ISIS software is performed.","PeriodicalId":260469,"journal":{"name":"2017 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129392129","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}
