A CMOS lineal magnetic Hall sensor front\u2010end working in current mode with programmable gain stage is designed and implemented with SMIC 55\u2009nm standard CMOS technology. By using a spinning\u2010current technique, chopper technique, and digital calibration technique to eliminate the offset voltage and nonlinearity, this magnetic Hall sensor can be easily integrated into digital systems like SoCs. This work has already finished the circuit simulation and layout design, and all simulation indicators basically reach the expected value. The maximum gain of proposed sensor systems can be up to 33.9\u2009dB. The total power is less than 4\u2009mW. And the total area is less than 0.113\u2009<jats:italic>\u03bc<\/jats:italic>m<jats:sup>2<\/jats:sup>. The magnetic Hall sensor can be easily integrated into chips such as the power Internet of Things to form a single\u2010chip\u2010level SoC design, which is mainly used in applications such as circuit breakers and electric energy measurement.<\/jats:p>","DOI":"10.1155\/2021\/6618206","type":"journal-article","created":{"date-parts":[[2021,2,2]],"date-time":"2021-02-02T20:23:24Z","timestamp":1612297404000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Design of a CMOS Lineal Hall Sensor Front\u2010End Working in Current Mode with Programmable Gain Stage for Power Specific Chip"],"prefix":"10.1155","volume":"2021","author":[{"given":"Peng","family":"Li","sequence":"first","affiliation":[]},{"given":"Wei","family":"Xi","sequence":"additional","affiliation":[]},{"given":"Xianggen","family":"Yin","sequence":"additional","affiliation":[]},{"given":"Hao","family":"Yao","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8221-1255","authenticated-orcid":false,"given":"Huafeng","family":"Chen","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2021,2,2]]},"reference":[{"key":"e_1_2_7_1_2","doi-asserted-by":"crossref","unstructured":"ShenY.andZhangR.
