The differential gudzazwi somumwe zvinokosha mune zvemagetsi nematunhu

In magadzirirwo zvigadzirwa nematunhu zvinowanzoitika nokuchinja kukuru umo kuchinja chaizvo misimboti kwezvisikwa zvakasiyana siyana namano. echimurenga kuchinja izvi kunogona kuitika sezvo pamusana kwaita itsva mano uye kukura kwezvinhu. A wakanaka iyi ichava kuchinja kubva Vacuum sepombi kune semiconductors. Kana kukura redunhu design, yakavakirwa zvinokwanisika pairi kuti asimbise inobudirira nekubata itsva mano. The differential gudzazwi achiri ichangopfuura, asi pakarepo akava ari kudiwa mumaindasitiri zhinji. Zvirongwa vachishandisa amplifiers aya zvinowanzoshandiswa maindasitiri Electronics. Kubva kwavari, zvakagadzirirwa midziyo yakawanda kumba, tepi vanyori, amplifiers, etc.

Nheyo nokushanda gudzazwi iri nyore, uye iri riri zvinobatsira mudziyo. It unotora mbiri zvinoshandisa pakurima / outputs uye ane yakakwirira pfuma coefficient.

The differential gudzazwi ndiyo vanoteerera musiyano mazano potentials ari kuonekwa goho voltage. The goho pamwero akaenzana dzingangoitika musiyano panguva Inlet, kane inoponesa yacho gudzazwi. Mune mamwe mazwi, zano rakadaro achaedza kudzorera kwokutanga zvakanyatsoenzana potentials pa mazano, nokuwedzera ufanane goho voltage. pfuma iyi zvikuru kushandiswa pakuvaka matunhu akasiyana. The differential gudzazwi aiva harbinger ari kubuda kubva operative amplifiers (numéro-BSN), izvo zvave chaizvo siyana zvemagetsi matunhu.

Op amps vakawana mukurumbira zvikuru uye zvakanaka basa. Small, chiine mukuru-nokukurumidza mudziyo chakasimbiswa kwazvo iri paindaneti mumatunhu akashandiswa kudzora siyana rwokugadzira kwendangariro. Pokugara anogona kuonekwa uye mumhuri midziyo yemagetsi. A dzakawanda nematunhu avo kushandiswa.

Somuenzaniso, nhamba yacho gudzazwi anogona kuitwa nyore kudzoreka, kana iwe kusika dzinovaka. Kubatanidza ichi goho / chiyamuro redunhu kuburikidza vakaomerwa nemishonga. The chiyamuro chiratidzo riri vakapfuura vakaomerwa resistor. Sezvaunogona kuona, kuti operative gudzazwi zviri nyore kuti nyoreka ari coefficient redunhu Saka vakaverenga reshiyo pamusoro inofambiswa kuramba aizviti kukosha mazano resistor.

Kana chinhu ichi chinoitwa akaenzana kubatana, uye kupa inofambiswa kuburikidza inverted chiyamuro, unogona kuumba differential gudzazwi. Nokuda kwaizvozvi voltage panguva asiri inverting chiyamuro uchaguta kuburikidza imwe voltage mugoveri zvakaenzana chezita tsika resistors mune rimwe ruoko. Kuunganidza zano rakadaro, tawana differential gudzazwi panguva pokuvanda. By kusiyanisa nhamba resistors vanogona kupesvedzera parameters kwemutariri yose. The mukuru, Chokwadi, ndiyo fuma.

Kushandisa differential amplifiers mune zvemagetsi, zvinokwanisika kuti vabudirire Implementation kuti chero basa. Vari zvakanaka aizvibata kufunga nematunhu, kuchengetedzwa zvakanaka kana.

Zvazvakashatira mumatunhu ari Os zvinosanganisira chiduku vasakukurwa iri goho chiratidzo zvichienderana tembiricha nokushanda kwadzinoita ari mudziyo. dambudziko iri kugadziriswa kushandisa dzakasiyana-siyana redunhu zvakagadzirwa.
