The high PSR is implemented with an adaptive supply\u2010ripple cancellation (ASRC) technique. The proposed ASRC circuit consists of a buffer with diode\u2010connected structure and an adjusting unit. The novel buffer introduces the supply ripple through the diode\u2010connected transistor to the gate of the pass transistor, enhancing the PSR in the range of 1\u00a0MHz. Additionally, the adjusting unit trims the current of the buffer continuously according to the magnitude of \n to optimize the PSR adaptively. Designed in a 55\u00a0nm CMOS process with an input voltage of 1.4\u00a0V, the proposed LDO achieves \u221269\u00a0dB and \u221255\u00a0dB PSR at 100\u00a0KHz and 1\u00a0MHz for 50\u00a0mA of \n, respectively. Moreover, the maximum current efficiency of the LDO is 99.8<jats:italic>%<\/jats:italic> at a full \n of 50\u00a0mA.<\/jats:p>","DOI":"10.1002\/cta.3942","type":"journal-article","created":{"date-parts":[[2024,1,25]],"date-time":"2024-01-25T09:54:56Z","timestamp":1706176496000},"page":"4199-4204","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["High PSR external capacitor\u2010less LDO with adaptive supply\u2010ripple cancellation technique"],"prefix":"10.1002","volume":"52","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4619-2525","authenticated-orcid":false,"given":"Siqiu","family":"Xu","sequence":"first","affiliation":[{"name":"National Key Laboratory of Materials for Integrated Circuits Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences  Shanghai China"},{"name":"University of Chinese Academy of Sciences  Beijing China"}]},{"given":"Chenchen","family":"Xie","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Materials for Integrated Circuits Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences  Shanghai China"}]},{"given":"Houpeng","family":"Chen","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Materials for Integrated Circuits Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences  Shanghai China"},{"name":"University of Chinese Academy of Sciences  Beijing China"}]},{"given":"Xi","family":"Li","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Materials for Integrated Circuits Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences  Shanghai China"},{"name":"University of Chinese Academy of Sciences  Beijing China"}]},{"given":"Zhitang","family":"Song","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Materials for Integrated Circuits Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences  Shanghai China"},{"name":"University of Chinese Academy of Sciences  Beijing China"}]}],"member":"311","published-online":{"date-parts":[[2024,1,25]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/TBCAS.2022.3223037"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1109\/TVLSI.2017.2742603"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2018.2841984"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1109\/TPEL.2021.3077013"},{"key":"e_1_2_7_6_1","doi-asserted-by":"crossref","unstructured":"GuptaV Rincon\u2010MoraGA RahaP.Analysis and design of monolithic high PSR linear regulators for SoC applications.
