Txoj kev daws teeb meem. Lub hom phiaj ntawm AC teeb liab amplifier Circuit Court yog kom stabilize DC biased input voltage rau lub amplifier thiab yog li tsuas yog amplify lub AC teeb liab yuav tsum tau. Lub emitter tsis kam muab qhov xav tau ntawm qhov tsis siv neeg biasing xav tau rau ib qho emitter amplifier.
Dab tsi yog qhov cuam tshuam ntawm emitter tsis kam hauv CE amplifier?
Rau cov lus qhia me me nws feem ntau xav tau khaws cia qhov loj voltage nce ntawm qhov yooj yim CE amplifier txawm tias ib qho emitter resistor siv rau DC stability. Qhov no tuaj yeem ua tau yog tias siv lub capacitor loj los hla lub teeb liab AC nyob ib ncig ntawm lub emitter resistor.
Vim li cas feem ntau siv emitter configuration?
Cov emitter transistors feem ntau yog siv dav, vim hais tias ib qho emitter transistor amplifier muab kev nce siab tam sim no, siab voltage nce thiab siab zog nce. Hom transistor no muab rau kev hloov me me hauv cov tswv yim muaj qhov hloov me me hauv cov zis.
Lub hom phiaj ntawm cov resistors txuas nrog lub hauv paus ntawm transistor hauv cov emitter amplifier yog dab tsi?
Tus emitter resistor pab ntau lub hom phiaj. Nws txhim kho qhov linearity ntawm amplifier, tsa cov input impedance, thiab ua kom yooj yim biasing.
siv cov emitter yog dab tsi?
Vim tias cov emitter txuas nrog hauv av, nws yog feem ntau rau cov teeb liab, tawm tswv yim thiab tawm. Qhov common-emitter Circuit Court yog qhov siv dav tshaj plaws ntawm kev sib tshuam, transistor amplifiers. Raws li kev sib piv nrog kev sib txuas ua ke, nws muaj ntau dua input impedance thiab qis tso zis impedance.
