The zero-potential scanning circuit can be divided into two groups based on type of row drivers. One type is a row driver using digital buffers. It can be easily implemented because of its simple structure, but we found that it can cause a large read-out error which originates from on-resistance of the digital buffers used in the row driver. The other type is a row driver composed of operational amplifiers. It, very accurately, reads the sensor resistance, but it uses a large number of operational amplifiers to drive rows of the sensor array; therefore, it severely increases the power consumption, cost, and system complexity. To resolve the inaccuracy or high complexity problems founded in those previous circuits, we propose a new row driver which uses only one operational amplifier to drive all rows of a sensor array with high accuracy. The measurement results with the proposed circuit to drive a 4 \u00d7 4 resistor array show that the maximum error is only 0.1% which is remarkably reduced from 30.7% of the previous counterpart.<\/jats:p>","DOI":"10.3390\/s16020155","type":"journal-article","created":{"date-parts":[[2016,1,26]],"date-time":"2016-01-26T10:00:42Z","timestamp":1453802442000},"page":"155","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":48,"title":["High-Accuracy, Compact Scanning Method and Circuit for Resistive Sensor Arrays"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2592-582X","authenticated-orcid":false,"given":"Jong-Seok","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Electronic Engineering, Hanyang University, 222 Wangsimni-ro, Deongdong-gu, Seoul 04763, Korea"}]},{"given":"Dae-Yong","family":"Kwon","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Hanyang University, 222 Wangsimni-ro, Deongdong-gu, Seoul 04763, Korea"}]},{"given":"Byong-Deok","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Hanyang University, 222 Wangsimni-ro, Deongdong-gu, Seoul 04763, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2016,1,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"213","DOI":"10.1016\/S0924-4247(02)00336-9","article-title":"Active tactile sensor for detecting contact force and hardness of an object","volume":"103","author":"Shikida","year":"2003","journal-title":"Sens.
