Imiba echaphazelayo yempazamo yenkqubo yeii-photodetectors
Zininzi iiparameters ezinxulumene nempazamo yenkqubo yeefotodetectors, kwaye eyona ngqwalasela iyahluka ngokweeprojekthi ezahlukeneyo. Ke ngoko, uMncedisi woPhando we-JIMU we-Optoelectronic waphuhliswa ukunceda abaphandi be-optoelectronic basombulule ngokukhawuleza impazamo yenkqubo ye-photodetectors kunye nokwakha ngokukhawuleza iinkqubo ze-optoelectronic, ngaloo ndlela benciphisa umjikelo weprojekthi kwaye banqande ukuqala ukusuka ekuqaleni ukuhlalutya kunye noyilo.
3. Ukuchasa
(1) Ixabiso lokuchasana: Ukukhethwa kwamaxabiso afanelekileyo okuchasa kubandakanyeka kwi-amplification factor of operational amplifiers, ukumelana nokulinganisa, i-RC filtering, njl. Ixabiso lokuchasana akufanele libe likhulu kakhulu, njengoko likhulu ixabiso lokumelana, ubuthathaka bomqondiso, ubuthathaka bokusebenza kokuchasana, kunye nomsindo omkhulu we-Gaussian omhlophe. Akufunekanga ibe ncinci kakhulu, njengoko ukusetyenziswa kwamandla kuya kwanda kwaye kunokuvelisa ubushushu kwaye kuchaphazele ixesha lokuphila.
(2) Amandla: Qinisekisa ukuba i-P = I ^ 2 * R ayidluli amandla ayo alinganisiweyo, kwaye ukuthintela i-resistor ekushiseni, akufanele idlule isiqingatha samandla ayo alinganisiweyo.
(3) Ukuchaneka: Kunempembelelo encinci ekuchanekeni kwenkqubo yokuhlaziya.
(4) Ukukhukuliseka kobushushu: Ukukhukuliseka kobushushu bezinto ezixhathisayo yinto ebalulekileyo yokuqwalaselwa ekubaleni iimpazamo ezicwangcisiweyo.
4. I-Capacitor
(1) Ixabiso leCapacitance: Kwiisekethe ezinxulumene ne-RC filt, i-constants yexesha, njl., ixabiso le-capacitance kufuneka libalwe ngokuchanekileyo. Uyilo lwesixokelelwano alunakulihoya ixesha elingaguqukiyo lokumiselwa komqondiso nje ukuhluza uphazamiseko lwamaxesha. Kuyimfuneko ukuba kuthathelwe ingqalelo iimfuno zombini i-domain ye-frequency kunye ne-domain yexesha ngaxeshanye ukuhlangabezana neemfuno zokucoca kunye nexesha lokusekwa komqondiso.
(2) Ukuchaneka: Ukuba isicelo sakho sihambelana neempawu ze-high-frequency okanye zifuna i-bandwidth ephezulu yokucoca, kufuneka ukhethe i-capacitors ngokuchaneka okuphezulu. Ngokuqhelekileyo, iimfuno ezichanekileyo zee-capacitors azibonakali kakhulu.
(3) Ukukhukuliseka kobushushu.
(4) Ukuchasana noxinzelelo: Kufuneka kuhlangabezane neendlela zokuyila ukuhla, kunye ne-20% yokunciphisa umda wesicelo jikelele.
4. Ubushushu bokusebenza
(1) Ukugqiba uluhlu lweqondo lokushisa olusebenzayo ngokusekelwe kwiimfuno zemveliso ye-photodetector. Umzekelo: Uluhlu lweqondo lokushisa lokusebenza lwe-IVD ethile yonyangoimveliso photodetectoryi 10 ukuya ku 30℃. Le mfuneko yobushushu ibaluleke kakhulu kuba iiparitha ezinxulumene nokukhukuliseka kweqondo lokushisa lamacandelo afana ne-amplifiers yokusebenza, i-resistors, kunye ne-ADCs ekhankanywe ngaphambili zonke zihlobene ngokusondeleyo neemfuno zokushisa zokusebenza kwemveliso. Ukuthathela ingqalelo udidi lomahluko weqondo lobushushu kunye neempembelelo zomahluko weqondo lobushushu phantsi kweemeko zokusingqongileyo ezisetyenziswayo, kuyaqinisekiswa ukuba impembelelo ebanzi yotshintsho kwipharamitha nganye ngaphakathi kolu luhlu lobushushu ayidluli imfuneko yokugqibelainkqubo photoelectricimpazamo.
(2) Qinisekisa ukuba ngaba kukho amacandelo anobume kunye nokuba iimfuno zendawo yokufuma ziyafezekiswa: Qinisekisa uluhlu lweenguqu zomswakama kwindawo yokusebenza kunye neeparitha zezixhobo ezithintekayo zokufuma ezichaphazela iziphumo.
5. Ukuzinza kunye nokuthembeka kwenkqubo kuhambelana nokuyila ukuzinza kwe-photodetector. I-prerequisite yokwenza izibalo zempazamo zenkqubo efanelekileyo kukuba inkqubo izinzile kwaye akufanele ichaphazeleke yi-EMC-related environment; kungenjalo, zonke izibalo azinantsingiselo. Ngenxa yokunqongophala kwendawo, esi sahluko asisayi kucacisa ngakumbi. Le miba mibini ilandelayo kufuneka iqwalaselwe ikakhulu. Kuyilo lwesekethe, ingqwalasela engqongqo yokukhusela kunye namanyathelo okuphepha kufuneka athathwe kwi-EMI kunye ne-EMS. B. I-casing, ukukhusela iingcingo zokudibanisa, iindlela zokumisa, njl njl. Kufuneka zihlalutywe kwaye ziqinisekiswe.
