Kev tsim Circuit Court tuaj yeem ua rau txaus ntshai vim tias yam hauv kev muaj tiag yuav txawv dua li qhov peb nyeem hauv phau ntawv. Nws yog qhov pom tseeb tias yog tias koj xav tau qhov zoo ntawm kev tsim hluav taws xob koj yuav tsum nkag siab txhua yam khoom thiab xyaum ua ntau yam. Tab sis muaj ntau cov lus qhia uas cov tsim qauv yuav tsum paub txhawm rau tsim cov kab hluav taws xob uas yuav ua tau zoo tshaj plaws thiab ua haujlwm tau zoo.

Kuv tau sim kuv qhov zoo tshaj plaws los piav qhia cov lus qhia hauv Phau Ntawv Qhia no tab sis rau ob peb lub tswv yim koj yuav xav tau kev piav qhia me ntsis kom tau txais nws zoo dua. Txog lub hom phiaj ntawd kuv tau ntxiv cov ntaub ntawv nyeem ntxiv hauv yuav luag txhua cov lus qhia hauv qab no. Yog li tsuas yog hauv qhov xwm txheej yog tias koj xav tau kev piav qhia me ntsis ntxiv hais txog qhov txuas lossis tshaj tawm lawv hauv cov lus hauv qab no. Kuv yuav nco ntsoov piav kom zoo tshaj qhov kuv ua tau.

Ua siab zoo txheeb xyuas kuv lub vev xaib www.gadgetronicx.com, yog tias koj txaus siab rau hauv hluav taws xob hluav taws xob, kev qhia thiab Cov Haujlwm.

Capacitor tau paub zoo txog nws lub sijhawm khoom, txawm li cas los xij kev lim dej yog lwm qhov khoom tseem ceeb ntawm cov khoom siv no uas tau siv los ntawm cov tsim qauv hauv Circuit Court. Yog tias koj tsis paub nrog Capacitors, Kuv qhia koj kom nyeem phau ntawv qhia no qhia txog Capacitors thiab yuav siv nws li cas hauv kev sib txuas

DECOUPLING CAPACITORS:

Cov khoom siv fais fab tsis ruaj khov tiag tiag, koj yuav tsum khaws qhov ntawd hauv koj lub siab. Txhua lub zog siv hluav taws xob thaum los txog rau lub neej yuav tsis ruaj khov thiab feem ntau cov hluav taws xob tau txais yuav hloov pauv tsawg kawg li ob peb puas zeb volts. Peb feem ntau tsis tuaj yeem tso cai rau qhov hloov pauv ntawm qhov hluav taws xob thaum ua kom muaj zog ntawm peb lub Circuit Court. Vim tias qhov hloov pauv hluav taws xob tuaj yeem ua rau kev ua haujlwm tsis raug thiab tshwj xeeb tshaj yog thaum los txog rau cov tswj hwm microcontroller muaj txawm tias muaj kev pheej hmoo ntawm MCU hla cov lus qhia uas tuaj yeem ua rau muaj kev puas tsuaj.

Txhawm rau kov yeej cov neeg tsim qauv no yuav ntxiv lub tshuab hluav taws xob ua ke thiab ze rau lub zog xa khoom thaum tsim hluav taws xob. Yog tias koj paub yuav ua li cas lub tshuab hluav taws xob ua haujlwm koj yuav paub, los ntawm kev ua lub tshuab hluav taws xob no yuav pib them los ntawm lub zog xa khoom kom txog thaum nws mus txog qib VCC. Thaum Vcc qib mus txog tam sim no yuav tsis hla dhau lub hau thiab nres them. Lub capacitor yuav tuav tus nqi no kom txog thaum muaj qhov poob qis los ntawm lub zog xa khoom. Thaum qhov hluav taws xob los ntawm cov khoom siv, qhov hluav taws xob hla cov phiaj ntawm lub capacitor yuav tsis hloov tam sim ntawd. Lub sijhawm tam sim no Capacitor yuav them nyiaj tam sim rau qhov poob qis los ntawm kev muab los ntawm kev muab tam sim no los ntawm nws tus kheej.

Ib yam li thaum qhov hluav taws xob hloov pauv tsis li tsim qhov ntsuas hluav taws xob nrawm hauv cov zis. Tus Capacitor yuav pib them nqi nrog kev hwm rau qhov ntsia hlau loj thiab tom qab ntawd tso tawm thaum ua kom qhov hluav taws xob hla nws ruaj khov yog li qhov ntsia hlau loj yuav tsis ncav cuag cov nti yog li ua kom ruaj khov ua haujlwm.

COUPLING CAPACITORS:

Cov no yog cov capacitors uas tau siv dav hauv cov tshuab hluav taws xob. Tsis zoo li decoupling capacitors yuav nyob rau hauv txoj kev ntawm lub teeb liab nkag. Ib yam li lub luag haujlwm ntawm cov khoom siv hluav taws xob no yog qhov sib txawv ntawm qhov kev txiav txim siab hauv ib qho Circuit Court. Coupling capacitors thaiv tawm lub suab nrov qis lossis DC lub hauv paus teeb liab. Qhov no yog ua raws qhov tseeb tias DC tam sim no tsis tuaj yeem hla dhau lub capacitor.

Kev txiav tawm lub tshuab hluav taws xob tau siv ntau hauv Amplifiers vim nws yuav txwv DC lossis qis dua lub suab nrov hauv lub teeb liab thiab tso cai tsuas yog siv lub teeb liab loj siv tau los ntawm nws. Txawm hais tias qhov ntau zaus ntawm kev txwv lub teeb liab nyob ntawm tus nqi ntawm lub tshuab hluav taws xob vim tias kev ua haujlwm ntawm lub tshuab hluav taws xob sib txawv rau ntau qhov sib txawv. Koj tuaj yeem xaiv lub capacitor uas haum rau koj xav tau.

Ntau zaus koj xav tau tso cai los ntawm koj lub capacitor qis dua tus nqi hluav taws xob ntawm koj lub Capacitor yuav tsum yog. Piv txwv li txhawm rau tso cai 100Hz teeb liab koj tus nqi hluav taws xob yuav tsum nyob ib puag ncig 10uF, txawm li cas los xij tso cai 10Khz teeb liab 10nF yuav ua haujlwm. Ib zaug ntxiv qhov no tsuas yog kwv yees kwv yees ntawm qhov muaj nuj nqis cap thiab koj yuav tsum tau suav qhov reactance rau koj lub teeb liab zaus siv cov mis 1 / (2 * Pi * f * c) thiab xaiv lub capacitor uas muaj tsawg dua reactance rau koj lub teeb liab xav tau.

"Lub xeev ntab yuav tsum zam txhua lub sijhawm", peb feem ntau hnov qhov no thaum tsim cov phiaj xwm digital. Thiab nws yog txoj cai kub uas koj yuav tsum ua raws thaum tsim qee yam uas cuam tshuam nrog digital IC's thiab hloov pauv. Txhua qhov digital IC's ua haujlwm ntawm qee qib kev xav thiab muaj ntau tsev neeg logic. Tawm ntawm cov TTL thiab CMOS no zoo nkauj npaum li paub.

Cov logic qib no txiav txim siab qhov hluav taws xob nkag hauv digital IC los txhais nws li 1 lossis 0. Piv txwv nrog +5V li Vcc qhov ntsuas hluav taws xob qib 5 txog 2.8v yuav raug txhais ua Logic 1 thiab 0 txog 0.8v yuav raug txhais raws li Logic 0. Txhua yam uas poob hauv qhov ntsuas hluav taws xob ntawm 0.9 txog 2.7v yuav yog thaj av uas tsis tau txiav txim siab thiab lub nti yuav txhais ib yam li 0 lossis zoo li 1 peb tsis tuaj yeem qhia tiag.

Txhawm rau zam qhov xwm txheej saum toj no, peb siv cov tshuaj tiv thaiv los txhim kho qhov hluav taws xob hauv cov pins nkag. Rub cov neeg tawm tsam txhawm rau txhim kho qhov hluav taws xob ze rau Vcc (qhov poob qis tshwm sim vim qhov ntws tam sim no) thiab Rub cov neeg tawm tsam kom rub qhov hluav taws xob ze rau GND pins. Txoj hauv kev no lub xeev ntab hauv cov tswv yim tuaj yeem zam tau, yog li zam peb cov IC IC los ntawm kev coj ua tsis raug.

Raws li kuv tau hais cov no rub tawm thiab rub qis tus tiv thaiv yuav tuaj yeem siv tau rau Microcontrollers thiab Digital chips, Tab sis nco ntsoov tias ntau lub MCU niaj hnub no tau nruab nrog rub sab hauv thiab rub tawm cov tshuaj tiv thaiv uas tuaj yeem qhib tau siv cov cai. Yog li koj tuaj yeem tshawb xyuas cov ntaub ntawv rau qhov no thiab xaiv los siv lossis tshem tawm rub tawm / nqis resistors raws li.
