In this proposed structure, a minimum of 430 V isolation is satisfied from on-chip intermetal SiO2 layers. On the high-voltage side, an adjustable gain amplifier that supports ±2.5 V of differential voltage drives the coil. However, on the low-voltage side, a CMOS integrated magnetic field sensitive MOSFET (MAGFET) placed under the coil converts the generated magnetic field into a current imbalance which will be transformed to a differential voltage via a cascode stage. In addition, based on the ADC input dynamic range, the signal amplitude is adjusted by using a 6-bit dB-linear programmable gain amplifier (PGA) with a gain range of 0 to 54 dB and a maximum gain-nonlinearity error of 0.2 dB. This PGA has a temperature independent characteristic with a maximum gain error of 0.21 dB over a temperature variation between −40 to 80 °C. The design achieves a low input offset of 0.18 mV. It has also a low current consumption of 1.2 and 2.3 mA for the high voltage and the low voltage side, respectively.","PeriodicalId":135163,"journal":{"name":"2020 18th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123080238","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}

Capacitively-Coupled ECG (ccECG) promises to allow physicians to perform ECG through clothing or unprepared skin, without conductive gel. However, as the patient moves, air gaps are created between electrodes and the skin. Thus, the total interface capacitance varies during ccECG measurements giving rise to motion artifacts (MA). To mitigate this issue, a circuit implementing negative feedback through the human body is proposed. The system relies on the principle that the coupling capacitance and input capacitance forms a gain stage which changes as motion happens. By adding the feedback stage, this gain is stabilized. When the coupling capacitance is swept from 100 nF to 1 pF in Spice simulation, within a frequency range of 500 mHz to 100 Hz, the system gain fluctuations are reduced from 12 dB (open-loop) down to 2 dB using the proposed technique. The proposed system can maintain the same bandwidth, similar settling time and does not present instability for the desired gain and frequency range.","PeriodicalId":135163,"journal":{"name":"2020 18th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130701534","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}

Hence, indirect voltage measurements are required. To perform these measurements programmable DC voltage sources are essential. An area efficient technique in generating DC voltage sources is the one that saves a ΣΔ bitstream generated in software in the memory of an ATE and apply it periodically to a low-pass filter (LPF). The Noise Transfer Function (NTF) of the ΣΔM has been selected from the Butterworth, Butterworth with zeros, Bessel and Gaussian families for ΣΔM orders from 1 to 4. An investigation was conducted to figure out the best ΣΔM type and order that should be used. It will be shown that using a high-order Butterworth-based ΣΔ bitstream yields the lowest settling time. This means the DC voltage levels will be available for usage quicker than the other ΣΔM types. Hence, reducing the time taken to test an IC, which in-turn minimizes the time to market and maximizes profit margins.","PeriodicalId":135163,"journal":{"name":"2020 18th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132721784","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}
