Kev tsim Circuit Court yog qhov tseem ceeb ua rau kev ua tau zoo tshaj ntawm lub sensor. Txij li thaum cov zis ntawm lub cim yog lub cim me me, yog tias cov txiaj ntsig tseem ceeb tau dhau los ntawm lub suab nrov, nws yuav tsis tsim nyog poob, yog li nws yog qhov tshwj xeeb tshaj yog ntxiv dag zog rau kev tawm tsam los tiv thaiv tsim ntawm lub cim hluav taws xob. Ua ntej ntawd, peb yuav tsum to taub qhov chaw ntawm lub suab nrov Circuit Court ua kom pom txoj kev zoo dua los txo cov suab nrov. Nyob rau hauv dav dav, muaj xya lub ntsiab hom ntawm lub cim hluav taws xob Circuit Court ua suab nrov.
2. Lub suab nrov tua tsim los ntawm cov khoom siv hluav taws xob
Tus nqi tsub ntxiv nyob hauv thaj av no hloov vim yog qhov hloov ntawm qhov hloov ntawm qhov hluav taws xob ntawm cheeb tsam qhov chaw hla txoj kev sib tshuam ntawm qhov hluav taws xob semiconductor PN, thiaj li ua kom pom lub zog. Thaum cov ntawv thov rau pem hauv ntej voltage nce, cov xaim hluav taws xob nyob rau thaj tsam N thiab qhov nyob hauv thaj av P hloov mus rau thaj tsam depletion, uas yog sib npaug rau them lub capacitor. Thaum cov hluav taws xob pem hauv ntej tau raug txo qis, nws rov ua rau cov xaim hluav taws xob thiab qhov ua rau txav mus deb ntawm thaj chaw depletion, uas yog sib npaug rau lub zog tso tawm. Thaum rov qab qhov hluav taws xob hluav taws xob, qhov kev hloov pauv ntawm thaj chaw depletion tau rov qab. Thaum tam sim no ntws los ntawm cheeb tsam qhov teeb meem, qhov kev hloov no ua rau muaj kev hloov me me ntawm qhov tam sim no ntws los ntawm cheeb tsam barrier, yog li ua kom muaj suab nrov tam sim no. Qhov ntau ntawm lub suab tso tawm yog sib npaug rau qhov ntsuas kub thiab cov bandwidth Δf.
