This paper proposes a direct connection between an FPGA and a resistive array distributed in M rows and N columns, without the need of analog-to-digital converters to obtain resistance values in the sensor and where the conditioning circuit is reduced to the use of a capacitor in each of the columns of the matrix. The circuit allows parallel measurements of the N resistors which form each of the rows of the array, eliminating the resistive crosstalk which is typical of these circuits. This is achieved by an addressing technique which does not require external elements to the FPGA. Although the typical resistive crosstalk between resistors which are measured simultaneously is eliminated, other elements that have an impact on the measurement of discharge times appear in the proposed architecture and, therefore, affect the uncertainty in resistance value measurements; these elements need to be studied. Finally, the performance of different calibration techniques is assessed experimentally on a discrete resistor array, obtaining for a new model of calibration, a maximum relative error of 0.066% in a range of resistor values which correspond to a tactile sensor.<\/jats:p>","DOI":"10.3390\/s16020181","type":"journal-article","created":{"date-parts":[[2016,2,1]],"date-time":"2016-02-01T10:03:26Z","timestamp":1454321006000},"page":"181","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Accuracy and Resolution Analysis of a Direct Resistive Sensor Array to FPGA Interface"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1185-4864","authenticated-orcid":false,"given":"\u00d3scar","family":"Oballe-Peinado","sequence":"first","affiliation":[{"name":"Departamento de Electr\u00f3nica, Universidad de M\u00e1laga, Andaluc\u00eda Tech, Campus de Teatinos, M\u00e1laga 29071, Spain"},{"name":"Instituto de Investigaci\u00f3n Biom\u00e9dica de M\u00e1laga (IBIMA), M\u00e1laga 29010, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fernando","family":"Vidal-Verd\u00fa","sequence":"additional","affiliation":[{"name":"Departamento de Electr\u00f3nica, Universidad de M\u00e1laga, Andaluc\u00eda Tech, Campus de Teatinos, M\u00e1laga 29071, Spain"},{"name":"Instituto de Investigaci\u00f3n Biom\u00e9dica de M\u00e1laga (IBIMA), M\u00e1laga 29010, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8503-9593","authenticated-orcid":false,"given":"Jos\u00e9","family":"S\u00e1nchez-Dur\u00e1n","sequence":"additional","affiliation":[{"name":"Departamento de Electr\u00f3nica, Universidad de M\u00e1laga, Andaluc\u00eda Tech, Campus de Teatinos, M\u00e1laga 29071, Spain"},{"name":"Instituto de Investigaci\u00f3n Biom\u00e9dica de M\u00e1laga (IBIMA), M\u00e1laga 29010, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7167-2651","authenticated-orcid":false,"given":"Juli\u00e1n","family":"Castellanos-Ramos","sequence":"additional","affiliation":[{"name":"Departamento de Electr\u00f3nica, Universidad de M\u00e1laga, Andaluc\u00eda Tech, Campus de Teatinos, M\u00e1laga 29071, Spain"},{"name":"Instituto de Investigaci\u00f3n Biom\u00e9dica de M\u00e1laga (IBIMA), M\u00e1laga 29010, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9505-9141","authenticated-orcid":false,"given":"Jos\u00e9","family":"Hidalgo-L\u00f3pez","sequence":"additional","affiliation":[{"name":"Departamento de Electr\u00f3nica, Universidad de M\u00e1laga, Andaluc\u00eda Tech, Campus de Teatinos, M\u00e1laga 29071, Spain"},{"name":"Instituto de Investigaci\u00f3n Biom\u00e9dica de M\u00e1laga (IBIMA), M\u00e1laga 29010, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2016,2,1]]},"reference":[{"key":"ref_1","unstructured":"Tise, B.
