Through the analysis and comparison of traditional analog current trigger and digital current trigger structure, the feed\u2010forward current trigger structure is selected, which is composed of received signal strength indicator (RSSI) and variable gain amplifier (VGA), which achieves low power consumption, fast stabilization time, and wide dynamic range design. The received signal strength indicator adopts the form of approximate logarithmic amplifier, five\u2010stage double feedback loop structure, and realizes lower power consumption. In order to prevent the load current trigger from entering the speed saturation zone, a gain unit structure in which the superimposed current trigger is connected to the NMOS tube as the load is proposed. The test results show that the circuit has a good power consumption performance (1\u2009mW) and at the same time 56.8\u2009dB\/m sensitivity. In this paper, through the analysis of the current trigger system and the analysis and comparison of the existing variable gain amplifiers, the variable gain amplifier structure composed of the folded wireless sensing unit and the index control unit is adopted. In order to reduce the power consumption of the circuit and increase the output swing, a structure in which the two\u2010stage folding wireless sensor unit shares the controlled voltage\u2010to\u2010current part of the circuit is proposed. Aiming at the design requirements of the system, this article discussed in detail the architecture of the entire temperature measurement node and the design parameters of the chip and completed the overall architecture design of the chip. The simulation results of the steady\u2010state temperature rise of the electric heating field show that the circuit has achieved an input dynamic adjustment range of more than 60\u2009dB, the maximum power consumption is 1\u2009mW, and the linearity error is less than 0.5\u2009dB. The designed automatic gain control circuit is implemented in SMIC 0.18 cape CMOS process. The simulation results of the steady\u2010state temperature rise of the electric heating field show that the circuit has a 56\u2009dB input dynamic adjustment range within a linear error of 1.25\u2009dB, and the time constant is 7.55\u2009ms, and power consumption is 2.84\u2009mW. Through the steady\u2010state temperature rise simulation and test results of the electric heating field, the correctness of the design is verified and it meets the system requirements.<\/jats:p>","DOI":"10.1155\/2021\/8359504","type":"journal-article","created":{"date-parts":[[2021,10,1]],"date-time":"2021-10-01T05:30:26Z","timestamp":1633066226000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Simulation of Steady\u2010State Temperature Rise of Electric Heating Field of Wireless Sensor Circuit Fault Current Trigger"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0755-5685","authenticated-orcid":false,"given":"Yinan","family":"Zhao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinwu","family":"Zhuang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhihao","family":"Ye","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiliang","family":"Qian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fang","family":"Peng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,9,30]]},"reference":[{"key":"e_1_2_8_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/TBCAS.2020.2971066"},{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.scs.2018.08.021"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2020.3025586"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/JSEN.2018.2864539"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.apenergy.2017.12.125"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.3390\/s19010060"},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.enbuild.2020.109861"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.1109\/TIM.2019.2920184"},{"key":"e_1_2_8_9_2","doi-asserted-by":"publisher","DOI":"10.3390\/su13063405"},{"key":"e_1_2_8_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.enconman.2021.114487"},{"key":"e_1_2_8_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/er.4433"},{"key":"e_1_2_8_12_2","doi-asserted-by":"crossref","unstructured":"GaoK.
