On the other hand, when a wider low-pass filter bandwidth is employed (BW = 5 Hz), a sharp SNR peak close to the QTF parallel-resonant frequency is found for large values of R<sub>L<\/sub>&nbsp;(R<sub>L<\/sub>&nbsp;&gt; 2 M\u03a9), whereas for small values of R<sub>L<\/sub>&nbsp;(R<sub>L<\/sub>&nbsp;&lt; 2 M\u03a9), the SNR exhibits a peak around the QTF series-resonant frequency. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"> The  following link provides access to the article:   <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2023\/03\/155_micromachines-14-00619_2023.pdf\">http:\/\/polysense.poliba.it\/wp-content\/uploads\/2023\/03\/155_micromachines-14-00619_2023.pdf<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"1024\" height=\"850\" src=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2023\/03\/micromach-1024x850.png\" alt=\"\" class=\"wp-image-2612\" srcset=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2023\/03\/micromach-1024x850.png 1024w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2023\/03\/micromach-300x249.png 300w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2023\/03\/micromach-768x637.png 768w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2023\/03\/micromach.png 1571w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The PolySense team has just published&nbsp; a new article on Micromachines reporting on a theoretical study of the Signal-to-Noise Ratio trend in a voltage-mode read-out of Quartz Tuning Forks (QTFs), mainly focusing on the effects of (i) the noise contributions of both the QTF-equivalent resistor and the input bias resistor RL of the preamplifier, (ii) <a href=\"https:\/\/polysense.poliba.it\/index.php\/2023\/03\/08\/new-publication-on-micromachines\/\" rel=\"nofollow\"><span class=\"sr-only\">Leggi di pi\u00f9New Publication on Micromachines<\/span>[&hellip;]<\/a><\/p>\n","protected":false},"author":2,"featured_media":2614,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-2613","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-senza-categoria"],"_links":{"self":[{"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/posts\/2613","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/comments?post=2613"}],"version-history":[{"count":1,"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/posts\/2613\/revisions"}],"predecessor-version":[{"id":2615,"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/posts\/2613\/revisions\/2615"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/media\/2614"}],"wp:attachment":[{"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/media?parent=2613"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/categories?post=2613"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/tags?post=2613"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
