(1) Txhawm rau tau txais cov tswv yim ruaj khov Circuitack Circuitb, nws yog feem ntau tsim nyog siv cov khoom siv me me lossis daig caj dab sab nraum lub tswv yim sab nraud los muab buffrine thauj khoom.
(2) vim tias feem ntau ntawm cov hluav taws xob yog tsim los ntawm cov teeb meem-hom hluav taws xob thiab tam sim no, thiab ntau hom hluav taws xob sib txawv thiab tuaj yeem txo cov crosstalk. Kev ntsuas hluav taws xob (sib txawv channel)
(3) Tsis txhob siv cov lus qhia txog kev siv siab lossis cov khoom tawm uas muaj kev nkag siab heev rau hluav taws xob.
(4) Cov lus qhia thiab cov khoom lim dej yuav tsum muab tso rau ntawm kev sib txuas ntawm cov cable sab nraud. Vim yog cov khoom siv los tiv thaiv kab mob, txhua txoj hlua khi hauv cov txheej txheem tsis sib haum yuav tsum tau lim. Ib qho ntxiv, cov teeb liab kev teeb liab ua lossis hloov kho hom kev txiav txim siab converter thiab xav tau lim.
(5) EMC lim dej num yuav tsum siv, thiab txhua lub lim dej IC yuav yuav tsum txuas nrog lub zos 0 v Txhawb lub dav hlau. Zoo li cov kev sib xyaw digital, lub zog thiab hauv av siv cov pins ntawm analog muab sib xyaw ua ke xav tau cov rf decoupling. Txawm li cas los xij, kev sib tw sib xyaw ua ke feem ntau yuav tsum muaj lub zog tsis tshua muaj zog, vim tias lub zog tsis muaj zog, PSRR) RC lossis LC lim tau thov rau lub hwj chim analog ntawm txhua lub operational amplifier, piv thiab cov ntaub ntawv hloov dua siab tshiab. Lub ces kaum zaus ntawm lub zog lim yuav tsum them tus psrr kaum zaus thiab skew ntawm lub ntaus ntawv, yog li kom tau txais cov psrr uas yuav tsum tau ua haujlwm tag nrho.
(6) Yuav kom tau txais cov kab txawv txav, txhua txoj kev sib txuas yuav tsum muaj kev tiv thaiv los ntawm cov ntxaij lim dej khov kho lossis lwm cov kev sib cais (xws li kev sib cais photicelectric).
(7) EMC lim yuav tsum siv, thiab txhua yam txheej txheej IC IC yuav tsum txuas nrog lub zos 0 v Siv dav hlau.
(8) Rau cov phiajcim nrawm nrawm, cov kab kis kis yog tsim nyog raws li lawv cov kev sib txuas ntev thiab qhov kev sib txuas lus ntau tshaj plaws. Txawm tias cov cim hluav taws xob tsawg, kev muaj peev xwm tiv thaiv kab mob kis tau, tab sis yog tias tsis muaj cov nyhuv sib kis tau yooj yim yuav tshwm sim.
(9) Sab Nraud Lub Virmueback Vacrumback, tsis txhob siv cov voj voog ua haujlwm rau lim lossis tswj EMC's RF bandwidth, tab sis tsuas yog siv cov khoom tawg (nyiam RC ncig). Cov tswv yim tseem ceeb txoj kev yog qhov ua tau zoo tsuas yog thaum qhib-voj nce ntawm cov kev ua haujlwm yog ntau dua lub kaw-voj nce. Nyob rau hauv cov nquag ntau dua, cov lus teb tau tsis tuaj yeem tswj tau los ntawm kev sib xyaw Circuit Court.
(10) Cov tswv yim tseem ceeb hauv Circuit Share feem ntau xav tau ib tug me resistor (kwv yees li 560ω) hauv series, thiab txhua tus capress caproos yog ntau dua 10pf.
(11) Qee daim ICS tshwj xeeb tshwj xeeb rau RF teb, yog li nws yog feem ntau yuav tsum tau siv cov PCB me me ntawm lub pcb los tuav cov ntaub thaiv npog zoo li no. Thov saib xyuas kom ntseeg tau tias txoj siv cua txias tau nruab rau hauv qhov chaw.
(12) Qhov kev sib piv yuav tsum muaj hysteresis (cov lus pom zoo) los tiv thaiv cov zis tsis yog vim muaj suab nrov thiab cuam tshuam thiab oscillation ntawm qhov chaw so. Qhov ceev ntawm kev siv kev sib piv yuav tsum tsis pub tshaj qhov yuav tsum tau ua (khaws DV \/ DT nyob rau hauv cov uas yuav tsum muaj thiab tsawg li sai tau).
Analog circuits yuav luag yuav luag tag nrho cov hluav taws xob teb. Lub luag haujlwm paub txog cov hluav taws xob hluav taws xob cuam tshuam nrog analog circuits. Tus qauv tsim ntawm analog circuits feem ntau yog nyuaj dua li ntawm cov khoom lag luam digital, thiab theem ntawm cov neeg tsim qauv kuj tseem siab dua. Qhov no yog ib qho ntawm cov laj thawj vim li casalog circuit system yog cov nrov tshaj digital Circuit system.
