Nyob rau hauv high-ceev digital circuits thiabsiab ntau zausRF circuits, teeb liab kev ncaj ncees yog tus yuam sij rau kev ua tiav tsim {}}}}}}} imp imp imp-{for for rau eceuring teeb liab zoo.
Qhov tseem ceeb ntawm kev ua yuam kev
Impedance txuam yog lub thev naus laus zis los xyuas kom meej meej txog cov cim qhia txog kev sib kis tau, thiab crosstalk, yog li txo cov kab ke {}}
Kev tsim txom txoj kev
1.} Xaiv Xaiv: Xaiv cov txheej txheem tsim nyog yog thawj cov ntaub ntawv nrog kev sib txawv dielects constants tuaj yeem cuam tshuam tus nqi cuam tshuam sib txawv ntawmCov Ntawv Luam Ntawv Hluav Taws Xob. Piv txwv,Fr -4, Ceramics lossis rogers cov ntaub ntawv feem ntau siv cov ntaub ntawv txheej txheem .
2.} kab dav thiab txuas: los ntawm cov kab mob tawm tsam ib txwm muaj cov kab mob me me, thaum lub zog nqaim tau loj dua.
{{0 {}}} Siv dav hlau: hauv cov txheej txheem ntau txheej txheem (cov txheej txheem hluav taws xob feem ntau muaj rau cov teeb liab txheej yuav cuam tshuam impedance {}}
{{04. Cov qauv txheej txheem ntawm PCB txiav txim siab txog kev sib txuas ntawm cov txheej txheem sib piv, uas nyob rau hauv lem cuam tshuam impedance.
{{05.} los ntawm qhov tsim: los ntawm qhov tsim tau cov txheej txheem sib txawv, thiab lawv qhov loj me thiab txoj haujlwm tuaj yeem cuam tshuam hauv zos impredance.
6.} Kev sim ua haujlwm thiab hloov kho: Siv cov khoom siv ntsuas kev tsim khoom xws li TDR (lub sijhawm ua kom haum, lub tswv yim kev coj ua tau zoo ntxiv tuaj yeem ua tiav.
