For the advanced CMOS process, [Formula: see text]\/[Formula: see text] methodology is suitable to the long channel and short channel design in all transistor operation regions. Different from the classical PSO algorithm, the adaptive PSO algorithm features the better search efficiency and faster convergence speed over the global search. Two amplifiers were designed and implemented in a standard 0.11[Formula: see text][Formula: see text]m CMOS process using MATLAB and HSPICE. Using the thermal noise coefficient [Formula: see text] and the corner frequency [Formula: see text], this paper explored the noise design budget of low-power multistage amplifier in different saturation modes. Detailed optimization of the objective function and constraints are classified into the mono-objective case and the multi-objective case. The total running times of simulations are 5649 s and 6813 s while the errors are less than 9% and 10%, respectively. Compared with CODE, GA[Formula: see text]PF and DE[Formula: see text]PF algorithms, it can save more running time and improve the accuracy of the design. Moreover, it provides more design freedom for the trade-off among gain, the gain-bandwidth (GBW) product, noise and the phase margin under worst cases without extra tweaking. Not only can the methodology work in the 0.18[Formula: see text][Formula: see text]m CMOS process, but also be migrated to the 0.11[Formula: see text][Formula: see text]m CMOS process, even in the nanometer analog circuit. <\/jats:p>","DOI":"10.1142\/s0218126616501048","type":"journal-article","created":{"date-parts":[[2016,5,4]],"date-time":"2016-05-04T02:31:51Z","timestamp":1462329111000},"page":"1650104","source":"Crossref","is-referenced-by-count":2,"title":["Particle Swarm Optimization Design of Low-Power Multistage Amplifier using <i>g<\/i><sub>m<\/sub>\/<i>I<\/i><sub>D<\/sub> Methodology"],"prefix":"10.1142","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6990-5041","authenticated-orcid":false,"given":"Gengyu","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Electronic and Information Engineering, Tianjin University, 92 Weijin Road, Nankai District, Tianjin, 300072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xia","family":"Xiao","sequence":"additional","affiliation":[{"name":"School of Electronic and Information Engineering, Tianjin University, 92 Weijin Road, Nankai District, Tianjin, 300072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiangtao","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Electronic and Information Engineering, Tianjin University, 92 Weijin Road, Nankai District, Tianjin, 300072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaiming","family":"Nie","sequence":"additional","affiliation":[{"name":"School of Electronic and Information Engineering, Tianjin University, 92 Weijin Road, Nankai District, Tianjin, 300072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiyuan","family":"Gao","sequence":"additional","affiliation":[{"name":"School of Electronic and Information Engineering, Tianjin University, 92 Weijin Road, Nankai District, Tianjin, 300072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2016,6,21]]},"reference":[{"key":"S0218126616501048BIB001","volume-title":"Design of Analog Integrated Circuits and Systems","author":"Laker K.","year":"1994","edition":"1"},{"key":"S0218126616501048BIB004","doi-asserted-by":"publisher","DOI":"10.1109\/TCAD.2008.2006143"},{"key":"S0218126616501048BIB006","doi-asserted-by":"publisher","DOI":"10.1109\/4.44994"},{"key":"S0218126616501048BIB007","doi-asserted-by":"publisher","DOI":"10.1109\/5.899053"},{"key":"S0218126616501048BIB008","doi-asserted-by":"publisher","DOI":"10.1109\/4.535416"},{"key":"S0218126616501048BIB009","doi-asserted-by":"publisher","DOI":"10.1109\/4.597291"},{"key":"S0218126616501048BIB015","first-page":"28","volume":"45","author":"Dammak H.
