I-Capcicitance yokucisha ekuxhumekeni okuqinile kombuso:
Ipharamitha ebucayi ekudluliselwe kombuso okuqinile, njenge-Photomos®, i-Optomos®, izithombe, noma ukudluliselwa kwe-Mosfet, ama-CD ahamba ama-capacitance (avaliwe) phakathi komthombo nokuyala.Le pharamitha ibheka izinga lapho isiginali yomthombo ithonya khona i-Drain Post-Off.Imvamisa, amashidi wedatha e-solid-State ethengisa abhekise kulokhu njenge-cout.Kuyamangaza ukuthi ukushintshwa kwe-CMOS, le pharamitha ayihlali incobilika njalo;Kodwa-ke, umqondo wokuhlukaniswa okuhlukile ukhonza inhloso efanayo.Kukala ukuhlanganiswa kwesiginali kusuka emthonjeni kuya ku-Drain lapho inkinobho ingasebenzi.Ukuhlola kwethu kuzokwehla ekutholeni i-cout kusuka ekwahlukaniswe kwedwa, isinyathelo esibucayi sokuqhathanisa ukudluliselwa kwesimo esiqinile nama-CMO aguqukayo ngempumelelo.Lolu lwazi lubalulekile ekukhetheni ukushintshwa okulungile kwezicelo ezahlukahlukene.
Ukucisha imvamisa yokuhlanzeka
Thatha, ngokwesibonelo, ukushintshwa kwe-ADG5412 kusuka kumadivayisi we-Analog.Kubonisa ubudlelwane obujwayelekile bokuvama kwe-Off-solation versus (Umdwebo 1).Ingxenye ethokozisayo?Njengoba imvamisa yesiginali yomthombo ikhuphuka, i-off-solation incishise.Amasiginali afudumele aphezulu athambekele ekuvuzweni "kalula ku-Off switch's Drain.I-Preving kwi-Circuit efanayo ye-Circuit (Isibalo 2) iveza imininingwane ethokozisayo: I-CDS ye-Parasitic Capacitance CDS (off) amabhuloho lapho inkinobho ivaliwe, ivumela la masiko afudumele aphezulu.Lesi silinganiso salesi simo siwumqondo wokuvulwa kwedwa.
Ukulinganisa Ukuhlukaniswa Kwedwa:
Ukubhekana nokubalwa kwe-Off-Solation, siqala ngokukhipha amanani we-VS nama-VOUT kusuka ku-Test Circuit (Umdwebo 2).Lawa manani ahlanganisa ezilinganisweni ezithile.Okokuqala, sibheka umjikelezo njengesihlungi esiphakeme (Umdwebo 3), ukubeka isisekelo sokubala umsebenzi wokudlulisa.Ngokuluka ku-Source Voltage VS kanye nokungaphandle kwayo, umsebenzi ogcwele wohlelo oluphelele uyavela.Isiphetho?I-plugging lo msebenzi kwifomula ye-off-solate yehla ngemfihlakalo ye-CDS (off).Le ndlela ye-step-by-step ayiyona nje indlela - ibalulekile ngokufihla ngokunembile ama-CD (avaliwe) ngokususelwa ku-RL, imvamisa yesiginali f, kanye nokucisha imininingwane yokwahlukanisa.
I-CMOS Shintsha vs. SOLIL-State idlulisela:
Ukuqhathanisa ukushintshwa kwe-CMOS kanye nokudluliselwa kwesimo esiqinile kuba nokuthakazelisa lapho sihlola amanani we-CD (off) kuwo wonke amadivayisi we-Analog '.Isibonelo, i-ADG54XXX kanye ne-ADG52XX Series Boeast Hast Calices Amandla aze afike ku-44v, kuyilapho i-ADG14XX ne-ADG12XX Series Max Out ku-33V.Sisebenzisana nalezi zibalo kulwa ne-30v kuya ku-40V SOLIL-State-State-StateNgaphezu kwalokho, ukubala ama-ron kanye nama-CD (off) imikhiqizo kumbula ithonya le-switch on the signal kuzo zombili izifundazwe ezisebenzayo nezamafayili, ukusebenza ngokugqekeza okuphelele kokungahlukaniswayo.
Unqenqema lokushintshwa kwe-CMOS:
Ngezindlela eziningi, ama-CMOs ashintsha ama-SOLIINE SOLICE-State Kudluliselwa.Cabanga ngalokhu: Ukufakwa okujwayelekile kwedijithali kwamanje ukushintshwa kwe-CMOS ye-ADI kuyinto engu-1na, ephansi kakhulu kune-5ma phambili yamanje enconyelwe ama-diode asalayoLokhu kwenza ama-CMOs ashintshe kakhulu ekuphathweni okuqondile kwe-microcontroller GPIO.Ngokwengeziwe, isikhathi sokujika kwe-CMOS switch efana ne-ADG1412 yi-Swift 100ns, anciphise ama-millusgish ama-millulisecond wokudluliselwa kwesimo esiqinile.Futhi kunesikhundla esithe xaxa sokufaka iziteshi eziningi zokushintshana kwiphakheji elilodwa elihlangene.Isibonelo, i-ADGS1414D ifanelana neziteshi eziyi-8 ephaketheni elincane le-5mm × 4mm.
