LEEM-15 Zida Zoyesera za Makhalidwe a PN Junction
Chiyambi
Katundu wa semiconductor PN mphambano ndi chimodzi mwazinthu zofunika kwambiri mufizikiki ndi zamagetsi. Chipangizochi chimagwiritsa ntchito njira yoyesera kuyeza ubale womwe ulipo pakalumikizidwe ka mphambano ya PN ndi magetsi, kutsimikizira kuti ubalewu umatsata lamulo logawa kwakukulu, ndikuyesa Boltzmann nthawi zonse (imodzi mwazinthu zofunika kwambiri mufizikiki) moyenera, zomwe zimathandizira ophunzirawo kuti aphunzire njira yatsopano yoyezera pakadali pano. Chipangizochi chimapereka chida chosinthira chotenthetsera poyerekeza ubale wapakati pa mphambano ya PN ndi kutentha kwa thermodynamic T, kuti mupeze chidwi cha sensa, ndikuyerekeza kuti mupeze mphamvu yamagetsi pazinthu za silicon ku 0K. Zipangizozi ndizokhazikika komanso zodalirika, ndipo zili ndi zoyeserera zakuthupi zambiri, lingaliro lomveka bwino, kapangidwe kake koyenera komanso zotsatira zoyeserera molondola. Zipangizozi zimagwiritsidwa ntchito poyesa kuyesera kwakuthupi ndikupanga kafukufuku wamakoleji ndi mayunivesite.
Zoyesera
1. Chiyanjano pakati pa kufalikira kwa mphambano ya PN pakadali pano ndi mphamvu yolumikizirana chimayesedwa, ndipo ubalewu udzawonetsedwa kuti umatsata lamulo logawa mwachidziwitso popanga data;
2. Kusintha kwa Boltzmann kumayesedwa molondola (Vutoli lidzakhala lochepera 2%);
3. Phunzirani kugwiritsa ntchito zokuzira zamagetsi kuti mupange chosinthira chamagetsi chamagetsi kuti muyese mphamvu yofooka kuyambira 10-6A mpaka 10-8A;
4. Chiyanjano pakati pa mphamvu yolumikizana ya PN ndi kutentha chimayesedwa ndipo mphamvu yamagetsi yolumikizirana ndi kutentha imadziwika.
5. Pafupifupi kuwerengera kusiyana kwa mphamvu ya semiconductor (silicon) zakuthupi pa 0K.
Ndondomeko Zamakono
1. DC magetsi
Mphamvu yamagetsi yosinthika ya 0-1.5V DC;
Mphamvu yamagetsi yosinthira 1mA-3mA DC.
2. LCD muyeso gawo
Chiwonetsero cha LCD: ma pixel 128 × 64
Zizindikiro ziwiri zamagetsi zamagetsi osiyanasiyana: 0-4095mV, Resolution ratio: 1mV
Osiyanasiyana: 0-40.95V, Maonekedwe chiyerekezo: 0.01V
3. Chida choyesera
Amapangidwa ndi zokulitsa zamagetsi LF356, cholumikizira socket, potentiometer yamagetsi angapo, ndi zina zotero TIP31 ndi mtundu wa 9013 triode amalumikizidwa kunja.
4. chotenthetsera
Youma bwino mkuwa chosinthika chotenthetsera;
Kutentha kwakutentha kwamitundu imodzi: Kutentha kwapakati mpaka 80.0 ℃;
Maonekedwe chiwonetsero cha kutentha kutentha 0.1 ℃.
5. Zipangizo zoyezera kutentha
DS18B20 digito kachipangizo kutentha
