Lub differential amplifier raws li ib tug ntawm lub ntsiab tseem ceeb nyob rau hauv hluav taws xob circuits

Nyob rau hauv lub tsim ntawm hluav taws xob circuits feem ntau tshwm sim radical hloov nyob rau hauv uas hloov lub heev hauv paus ntsiab lus ntawm cov creation ntawm ib tug ntau yam ntawm pab kiag li lawm. Cov revolutionary kev hloov tej zaum yuav tshwm sim raws li ib tug tshwm sim ntawm cov emergence ntawm tshiab kiag li lawm thiab txoj kev loj hlob ntawm technology. Ib tug piv txwv zoo nyob rau hauv rooj plaub no yuav tsum tau rau txoj kev hloov los ntawm lub tshuab nqus tsev hlab semiconductors. Los yog nyob rau hauv txoj kev loj hlob ntawm Circuit Court tsim, raws li nyob rau hauv uas nws tseem tau los tsim kom muaj zoo ua hauj lwm ntawm tshiab kiag li lawm. Lub differential amplifier yog tus tsis ntev los no, tab sis tam sim ntawd ua nyob rau hauv kev thov nyob rau hauv ntau industries. Schemes siv cov amplifiers yog lug siv nyob rau hauv industrial electronics. Raws li rau lawv, tsim ntau lub tsev khoom siv, daim kab xev recorders, amplifiers, etc.

Lub hauv paus ntsiab lus ntawm cov lag luam ntawm lub amplifier yog yooj yim heev, thiab nyob rau hauv no dag lub chaw ntawm tus dais. Nws comprises ob inputs / outputs thiab muaj ib tug high nce coefficient.

Lub differential amplifier yog teb rau qhov txawv ntawm lub tswv yim potentials ntawm cov tsos ntawm cov zis voltage. Lub tso zis theem yog sib npaug zos rau lub peev xwm sib txawv nyob rau hauv cov inlet, multiplied los ntawm tus nce ntawm lub amplifier. Nyob rau hauv lwm yam lus, xws li ib tug tswvyim yuav sim los thawj zaug equilibrium potentials ntawm lub tswv yim, los ntawm nce lub theem ntawm cov zis voltage. Qhov no tej khoom vaj tse yog dav siv nyob rau hauv kev tsim kho ntawm txawv circuits. Lub differential amplifier yog ib tug harbinger ntawm lub rov tshwm sim ntawm ua hauj lwm amplifiers (op-amp), uas tau tau lug siv nyob rau hauv ntau yam hluav taws xob circuits.

Op amps muaj tau zoo chaw thiab zoo nyob rau hauv kev ua hauj lwm. Me me, compact high-ceev ntaus ntawv yog nyob ruaj khov nyob rau hauv lub tshuab hluav taws xob circuits siv rau cov kev tswj ntawm ntau yam hauj dab. Shelter yuav pom thiab nyob rau hauv khoom vaj khoom tsev. Ib tug loj tus naj npawb ntawm circuits nrog lawv siv.

Piv txwv li, qhov ratio ntawm cov amplifier yuav ua tau yooj yim forms, Yog hais tias koj tsim cov tswv yim. Yuav kom txuas no tso zis / tswv yim Circuit Court los ntawm cov txawj kuj. Lub tswv yim teeb liab yog tseem dhau los ntawm ib limiting resistor. Raws li koj tau pom, cov ua hauj amplifier yog ib qho yooj yim los mus ua kom tswj tau tus coefficient Circuit Court li xam piv ntawm lub tswv yim kam mus rau lub nominal tus nqi ntawm lub tswv yim resistor.

Yog hais tias qhov no zoo tshaj yog ua sib npaug zos rau kev sib sau, thiab muab tswv yim los ntawm cov inverted tswv yim, koj muaj peev xwm tsim ib tug differential amplifier. Rau lub hom phiaj no lub voltage ntawm qhov uas tsis yog-inverting tswv yim yog noj los ntawm ib tug voltage divider nrog sib npaug nominal qhov tseem ceeb ntawm resistors nyob rau hauv txhua phab caj npab. Sib sau ua ke xws li ib tug tswvyim, peb muab tau cov differential amplifier ntawm lub Shelter. By ua tus piv ntawm resistors muaj feem xyuam rau qhov tsis muaj tag nrho cov Circuit Court. Lub ntsiab, ntawm chav kawm, yog cov tau.

Siv differential amplifiers nyob rau hauv electronics, nws yog tau mus cuag qhov kev siv ntawm yuav luag txhua project. Lawv zoo coj ib yam nkaus nyob rau hauv logic circuits, kev tiv thaiv los yog kev tswj.

Qhov tsis zoo ntawm circuits rau lub OS xws li ib tug me me drift nyob rau hauv lub tso zis teeb liab nyob rau hauv lub kub hom kev lag luam ntawm tus dais. Qhov teeb meem no yog solved siv ib tug ntau yam ntawm Circuit Court tsim.
