Makhalidwe a Zamalonda

Kusintha kwa analogue 

Theanalogue(kapenaPETR)kusintha, amatchedwanso kutikusintha kwa mayiko awiri,ndi azamagetsichigawo chomwe chimachita mofanana ndi akutumiza, koma palibemagawo osuntha.Chinthu chosinthira nthawi zambiri chimakhala chaMOSFET ma transistors, chimodzi ndi chipangizo cha N-channel, chinanso chipangizo cha P-channel.Chipangizochi chimatha kuyendetsa ma analogi kapena ma digito mbali iliyonse chikayatsidwa ndikupatula ma terminals pomwe yazimitsa.Masiwichi a analogue nthawi zambiri amapangidwa ngatimabwalo ophatikizikam'maphukusi okhala ndi masiwichi angapo (nthawi zambiri awiri, anayi kapena asanu ndi atatu).Izi zikuphatikiza 4016 ndi 4066 kuchokera ku4000 mndandanda.

Kuyika kowongolera pa chipangizocho kungakhale chizindikiro chomwe chimasintha pakati pa ma voltages abwino ndi oipa, ndi mphamvu yowonjezera yowonjezera yomwe imayatsa chipangizocho ndikuzimitsa chipangizocho.Mabwalo ena amapangidwa kuti azilankhulana kudzera pa doko la serial ndi wowongolera wolandila kuti azimitsa kapena kuzimitsa.

Chizindikiro chomwe chikusinthidwa chiyenera kukhalabe m'malire a njanji zabwino ndi zoipa zomwe zimagwirizanitsidwa ndi ma terminals a P-MOS ndi N-MOS.Kusintha nthawi zambiri kumapereka kudzipatula kwabwino pakati pa siginecha yowongolera ndi ma siginecha / zotulutsa.Sagwiritsidwa ntchito pakusintha kwamagetsi apamwamba.

Zofunikira pakusintha kwa analogue ndi:

• on-resistance: kukana kukayatsidwa.Izi nthawi zambiri zimachokera ku 5ohmmpaka mazana angapo ohm.
• off-resistance: kukana pamene wazimitsidwa.Izi nthawi zambiri zimakhala ma megaohms kapena gigaohms.
• mtundu wa ma siginecha: ma voltages ochepera komanso apamwamba omwe amaloledwa kuti chizindikirocho chidutse.Ngati izi zapitilira, chosinthiracho chikhoza kuwonongedwa ndi mafunde ochulukirapo.Zosintha zakale zimatha ngakhalegwirani, zomwe zikutanthauza kuti akupitiriza kuyendetsa mafunde ochulukirapo ngakhale chizindikiro cholakwika chikachotsedwa.
• jekeseni wa ndalama.Izi zimapangitsa kuti kusinthaku kulowetse pang'onomtengo wamagetsimu siginecha ikayatsidwa, kuchititsa kakang'onospikekapenaglitch.Mtengo wa jakisoni umatsimikiziridwa mucoulombs.

Zosintha zaanalogue zimapezeka muzonse ziwirikudzera-bowo lusokapena pateknoloji yokwera pamwambaphukusi.

Kusintha kwa analogi ndikusintha komwe kumagwiritsa ntchito mawonekedwe a JFET kapena MOS kuwongolera njira yolumikizira.

Kusintha kwa analogi ndikusintha komwe kumagwiritsa ntchitomawonekedwe a JFETkapenaMOSkuwongolera njira yazizindikiro, ndipo imagwiritsidwa ntchito makamaka pomaliza ntchito yosinthira yolumikizira ulalo wa chizindikiro kapena kuchotsedwa.Chifukwa cha kuchepa kwa mphamvu yamagetsi, kuthamanga kwachangu, osalumikizana ndi makina, kukula kochepa komanso moyo wautali wautumiki, wakhala akugwiritsidwa ntchito kwambiri m'machitidwe osiyanasiyana odzilamulira okha ndi zipangizo zamagetsi zamagetsi.

Kapangidwe kakusintha kwa analogi yachikhalidwe cha CMOS kukuwonetsedwa mu Chithunzi 1. Kulumikiza NMOS ndi PMOS molumikizana kumapangitsa kuti zizindikilo zizidutsa bwino mbali zonse ziwiri.Chipata chimagwiritsidwa ntchito kuwongolera kutembenuka ndi kutseka kwa switch.NMOS imayatsa Vgs ikakhala yabwino, ndikuzimitsa Vgs ikakhala kuti alibe, ndipo PMOS imachita zosiyana.Chifukwa cha mawonekedwe osiyanasiyana a PMOS ndi NMOS, chosinthira chomwe chimapangidwa ndi iwo chimakhala ndi mawonekedwe omwe akuwonetsedwa pachithunzichi.Kuchuluka kwa ma siginecha omwe amatengedwa pakati pa NMOS ndi PMOS kumatsimikiziridwa ndi kuchuluka kwa zolowetsa ndi voliyumu yotulutsa.Popeza kusinthaku kulibe vuto losankha njira yomwe ikuyenda panopa, palibe kusiyana pakati pa kulowetsa ndi kutulutsa.Ma MOSFET awiriwa amayatsidwa kapena kuzimitsidwa motsogozedwa ndi zosintha zamkati komanso zosasintha.Ubwino wa ma switch a CMOS ndikusintha kwa njanji kupita ku njanji, magwiridwe antchito a bidirectional, komanso kukaniza sikunasinthe mphamvu yamagetsi ikasintha.
