Hloov Circuit Court

Ntxiv rau kev siv los ua AC teeb liab amplifier, lub triode kuj tseem siv tau los ua qhov hloov. Hais lus nruj me ntsis, qhov kev txiav txim ntawm lub triode tsis zoo ib yam li qhov sib txuas ntawm cov khoom siv sib txuas, tab sis nws muaj qee cov yam ntxwv uas cov tshuab hluav taws xob tsis muaj. Tus yam ntxwv ntawm switching triodes nyob rau hauv saturated conduction xeev yog hais tias ob qho tag nrho cov emitter junction thiab lub collector junction yog nyob rau hauv pem hauv ntej bias. Tus yam ntxwv ntawm ib tug transistor nyob rau hauv lub amplified lub xeev yog hais tias lub emitter junction yog nyob rau hauv ib tug pem hauv ntej bias thiab lub collector junction yog nyob rau hauv ib tug rov qab bias. Qhov no kuj tseem yog lub hauv paus ntsiab lus uas koj tuaj yeem siv lub voltmeter los ntsuas qhov ntsuas qhov ntsuas hluav taws xob ntawm cov emitter junction thiab collector junction los txiav txim seb qhov kev ua haujlwm ntawm triode. Hloov cov triodes ua haujlwm raws li cov yam ntxwv hloov ntawm triodes.

Cov duab ntawm lub triode hloov yog tib yam li ntawm ib txwm triode. Nws ua haujlwm nyob rau hauv cheeb tsam txiav tawm thiab saturation, sib npaug rau kev txiav tawm thiab ua lub voj voog. Vim nws muaj peev xwm ua kom tiav qhov qhib thiab kaw ntawm circuits, nws yog dav siv nyob rau hauv ntau yam switching circuits, xws li feem ntau siv switching fais fab mov circuits, tsav circuits, high-frequency oscillation circuits, analog-to-digital conversion circuits, mem tes circuits. , thiab output circuits. Thaum qhov hluav taws xob siv rau lub emitter hlws ris ntawm lub triode yog ntau tshaj qhov conduction voltage ntawm PN hlws ris, thiab thaum lub sij hawm tam sim no ntawm lub hauv paus nce mus rau ib qho twg, lub collector tam sim no tsis nce nrog qhov nce ntawm lub hauv paus tam sim no, tab sis. tsis hloov ntau ze ntawm ib qho nqi. Lub sij hawm no, lub triode poob nws tam sim no amplification nyhuv, qhov voltage ntawm lub collector thiab emitter yog heev me me, thiab lub conduction lub xeev ntawm lub collector thiab emitter yog sib npaug rau qhov hloov, qhov no yog lub xeev conduction ntawm lub triode. Lub load resistor yog txuas ncaj qha nruab nrab ntawm lub collector ntawm lub transistor thiab lub hwj chim mov, thiab nyob rau ntawm lub ntsiab tam sim no Circuit Court ntawm lub transistor. Lub input voltage Vin tswj qhov qhib thiab kaw kev ua ntawm lub transistor hloov. Thaum lub transistor nyob rau hauv lub xeev qhib, lub load tam sim no yog thaiv, thiab conversely, thaum lub transistor nyob rau hauv lub xeev kaw, lub tam sim no yuav ntws.
