Siv ib qho kev sib txuas kom raug decoupling capacitor tuaj yeem cawm koj ntau yam teeb meem. Txawm hais tias koj lub voj voog ua haujlwm ntawm lub rooj ntev zaum yam tsis muaj kev sib txuas, nws tuaj yeem muaj teeb meem thaum koj mus rau hauv kev tsim khoom los ntawm cov txheej txheem sib txawv thiab lwm yam kev cuam tshuam hauv ntiaj teb tiag.

Vim li cas peb thiaj xav tau cov khoom siv hluav taws xob?

Ib lub decoupling capacitor ua raws li lub zog hluav taws xob hauv zos reservoir. Capacitors, zoo li cov roj teeb, xav tau sijhawm los them thiab tso tawm. Thaum siv los ua decoupling capacitors, lawv tawm tsam kev hloov pauv sai ntawm qhov voltage. … Decoupling capacitors yog siv los lim tawm qhov voltage spikes thiab dhau los ntawm tsuas yog DC tivthaiv ntawm lub teeb liab.

Puas yog txhua tus IC xav tau lub capacitor decoupling?

Nyob zoo txhua txhua IC yuav tsum muaj ib lub decoupling capacitor. Yog tias tsis muaj dab tsi tau teev tseg los ntawm daim ntawv teev npe, qhov tsawg kawg nkaus, muab 0.1 uF ceramic cap ze ntawm lub hwj chim tus pin ntawm IC, ntsuas tsawg kawg ob zaug ntawm qhov hluav taws xob uas koj siv. Ntau yam yuav xav tau ntau dua capacitance ntawm cov tswv yim.

Vim li cas thiaj tsim nyog?

Vim li cas thiaj tsim nyog decoupling? Decoupling muab txoj kev qis impedance los ntawm lub hwj huam mov mus rau hauv av. Yog li ntawd, xaiv qhov tsawg-inductance tab sis tus nqi siab capacitor (tsawg impedance) yog qhov tseem ceeb heev. Qhov cuam tshuam ntawm kev sib txuas capacitive ntawm txoj kev rov qab los tam sim no.

Pob op amps xav tau decoupling capacitors?

Zoo, nrog op amps, yog tias koj muaj lub suab nrov qis zog koj tsis txhobtiag tiag xav tau decoupling capacitors vim tias lawv tsis hloov nrawm thiab ua suab nrov ntawm pcb lem.
