Ua kom paub cov ntsiab lus ntawm triode
1. Lub cheeb tsam tua tawm tau xa cov hluav taws xob mus rau thaj chaw hauv paus
Lub zog hluav taws xob Ub yog thov rau emitter hlws ris ntawm lub resistor Rb, thiab lub emitter hlws ris yog mus rau tom ntej kev tsis ncaj ncees, thiab feem ntau cov nqa khoom (cov hluav taws xob dawb) hauv thaj av emitter txuas ntxiv hla emitter hlws ris mus rau hauv lub hauv paus cheeb tsam los tsim emitter tam sim no Ie Cov. Nyob rau tib lub sijhawm, feem ntau ntawm cov neeg nqa khoom hauv thaj chaw hauv paus tseem diffuse rau emitter thaj av. Txawm li cas los xij, vim hais tias feem ntau cov cab kuj siab yog ntau qis dua qhov kev thauj khoom siab hauv cheeb tsam emitter, qhov tam sim no tuaj yeem tsis quav ntsej. Yog li ntawd, nws tuaj yeem suav tias kev sib tshuam emitter feem ntau yog hluav taws xob hluav taws xob.
2. Diffusion thiab recombination ntawm cov khoom siv hluav taws xob hauv thaj chaw puag
Tom qab lub tshuab hluav taws xob nkag mus rau lub hauv paus cheeb tsam, nws yog ntom nti ze ntawm qhov sib txuam emitter, thiab maj mam tsim cov hluav taws xob tsom qhov sib txawv. Nyob rau hauv cov nyhuv ntawm qhov txawv ntawm cov concentration, cov hluav taws xob ntws tawm ua rau diffuse rau hauv cov khoom sib txuam hauv thaj av hauv cheeb tsam, thiab cov hluav taws xob hluav taws xob tau rub mus rau hauv lub collector tam sim no. Thaj av ntawd ua cov lwv tawm ntawm Ic. Kuj tseem muaj qhov feem me me ntawm cov hluav taws xob (vim tias thaj chaw thaj chaw yog heev nyias) recombined nrog lub qhov hauv thaj av hauv lub hauv paus, thiab qhov sib piv ntawm qhov sib txawv ntawm cov hluav taws xob ntws mus rau qhov sib cuam tshuam hluav taws xob ntws los txiav txim siab lub peev xwm ntawm triode.
3. Kev muab hluav taws xob hauv cheeb tsam tus khaws dej
Txij li qhov kev sib tshuam ntawm cov hluav taws xob ntxiv rau qhov hloov hluav taws xob yog qhov loj, lub zog hluav taws xob tsim los ntawm qhov hluav taws xob rov qab no yuav tiv thaiv cov hluav taws xob hauv cov cheeb tsam collector los ntawm kev sib txawv mus rau hauv thaj chaw hauv cheeb tsam, thiab tib lub sijhawm, cov hluav taws xob tsis zoo rau qhov chaw ze ntawm tus neeg sib sau. Kev sib tshuam yog rub mus rau hauv thaj chaw khaws khoom los tsim cov neeg siv lub ntsiab. Tam sim no Icn. Tsis tas li ntawd, cov tsheb thauj neeg tsawg (qhov) hauv thaj chaw khaws khoom kuj tseem tsim kev txav chaw, uas ntws mus rau thaj chaw hauv cheeb tsam los ua qhov rov qab tig rov qab tam sim no, uas yog sawv cev los ntawm Icbo, uas yog me me hauv qhov muaj nqis tab sis tsis tshua muaj siab kub.
