Guhindura Analogue 

Uwitekaanalogue(cyangwaPETR)hindura, naguhinduranya byombi, ni anibikoresho bya elegitoronikiibice bitwara muburyo busa na arelay, ariko ntaibice byimuka.Guhindura ibintu mubisanzwe ni couple yaBYINSHI transistors, kimwe igikoresho cya N-umuyoboro, ikindi igikoresho cya P-umuyoboro.Igikoresho kirashobora kugereranya cyangwa ibimenyetso bya digitale mubyerekezo iyo biri kuri kandi bigatandukanya itumanaho ryahinduwe iyo rizimye.Guhindura Analogue mubisanzwe bikorwa nkukoimiyoboro ihuriwehomubipaki birimo ibintu byinshi byahinduwe (mubisanzwe bibiri, bine cyangwa umunani).Harimo 4016 na 4066 kuva kuri4000 Urukurikirane.

Igenzura ryinjira mubikoresho rishobora kuba ikimenyetso gihinduranya hagati yumubyigano mwiza kandi utari mwiza, hamwe na voltage nziza ihindura igikoresho hamwe nibi bibi bizimya igikoresho.Izindi nzitizi zagenewe kuvugana binyuze ku cyambu gikurikirana hamwe n’umugenzuzi wakira kugira ngo ushyireho cyangwa uzimye.

Ikimenyetso cyahinduwe kigomba kuguma mu mbibi za gari ya moshi nziza kandi mbi zitangwa na P-MOS na N-MOS.Guhindura muri rusange bitanga kwigunga hagati yikimenyetso cyo kugenzura nibimenyetso byinjira / bisohoka.Ntabwo zikoreshwa muguhindura voltage nyinshi.

Ibyingenzi byingenzi bya analogue ihinduka ni:

• kuri-kurwanya: kurwanywa iyo ufunguye.Ibi bikunze kuva kuri 5ohmskugeza kuri magana make.
• off-resistance: kurwanywa iyo bizimye.Mubisanzwe ni umubare wa megaohms cyangwa gigaohms.
• urutonde rwibimenyetso: ntarengwa na voltage ntarengwa yemerera ibimenyetso kunyuramo.Niba ibi birenze, switch irashobora gusenywa numuyaga ukabije.Ubwoko bwa kera bwo guhinduranya burashobora ndetseshyira hejuru, bivuze ko bakomeje kuyobora imiyoboro ikabije na nyuma yikimenyetso kibi kivanyweho.
• inshinge.Ingaruka itera guhinduranya gutera akantu gatoamashanyarazimu kimenyetso iyo gifunguye, gitera gitospikecyangwaglitch.Gutera inshinge byerekanwe muricoulombs.

Guhindura Analogue birahari muri byombihifashishijwe ikoranabuhangacyangwa natekinoroji yubusoipaki.

Guhindura analogi ni switch ikoresha ibiranga JFET cyangwa MOS kugenzura inzira yikimenyetso.

Analog switch ni switch ikoreshaibiranga JFETcyangwaMOSkugenzura inzira yikimenyetso, kandi ikoreshwa cyane cyane kugirango urangize imikorere yo guhinduranya ibimenyetso bihuza cyangwa guhagarika.Kubera imbaraga nke zikoresha, umuvuduko wihuse, nta mikoreshereze yubukanishi, ingano ntoya nubuzima bwa serivisi ndende, yakoreshejwe cyane muri sisitemu zitandukanye zo kugenzura byikora hamwe nibicuruzwa bya elegitoroniki.

Imiterere ya gakondo ya CMOS igereranya igereranwa irerekanwa mumashusho 1. Guhuza NMOS na PMOS murwego rumwe bituma ibimenyetso bigenda neza neza mubyerekezo byombi.Irembo rikoreshwa mugucunga gufungura no kuzimya.NMOS ifungura iyo Vgs ari nziza, ikazimya iyo Vgs ari mbi, na PMOS ikora ibinyuranye.Bitewe nibintu bitandukanye biranga PMOS na NMOS, switch igizwe nabo ifite ibiranga bigaragara mumashusho hepfo.Ingano yerekana ibimenyetso bitwarwa hagati ya NMOS na PMOS igenwa nikigereranyo cyo kwinjiza nibisohoka voltage.Kubera ko switch idafite ikibazo cyo guhitamo icyerekezo cyubu, nta tandukaniro riri hagati yinjiza nibisohoka.MOSFETs ebyiri zifunguye cyangwa zizimye munsi yubugenzuzi bwimbere bwimbere no kudahindura.Ibyiza bya CMOS byahinduwe ni gari ya moshi-kuri-gariyamoshi, ibikorwa byombi, kandi kuri-kurwanya-ntigihinduka mugihe iyinjizwa rya voltage rihindutse.
