Can we consider diffusion capacitance as a parallel plate capacitor ? It is easier to see the depletion capacitance and its calculation but diffusion capacitance calculation is very confusing ? Does the on resistance comes from carrier scattering?<\/p>\n<div data-embedjson=\"{&quot;url&quot;:&quot;\/forum\/wp-content\/uploads\/forum-uploads\/579\/0CIXBUB9I0UA.pdf&quot;,&quot;name&quot;:&quot;Analysis in PN Junction Diode.pdf&quot;,&quot;type&quot;:&quot;application\/pdf&quot;,&quot;size&quot;:2941047,&quot;embedType&quot;:&quot;file&quot;}\">\n<a href=\"\/forum\/wp-content\/uploads\/forum-uploads\/579\/0CIXBUB9I0UA.pdf\" download aria-label=\"Analysis in PN Junction Diode.pdf\"><br \/>\nAnalysis in PN Junction Diode.pdf<br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-158521","topic","type-topic","status-closed","hentry","topic-tag-capacitance","topic-tag-pn-junction-simulation-1","topic-tag-resistance"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["590"],"_bbp_likes_count":["0"],"_bbp_subscription":["234509"],"_bbpmt_movedon":["2022-07-01 17:14:53"],"_bbpmt_movedfrom":["151970"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["158521"],"_bbp_forum_id":["27793"],"_bbp_engagement":["106247","190096"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["178864"],"_bbp_last_active_id":["178864"],"_bbp_last_active_time":["2021-05-31 03:30:35"]},"test":"tennywang"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/158521","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/158521\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=158521"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
