Ntawm tag nrho cov txheej txheem ntawm kev muab kev tsis ncaj ncees thiab ruaj khov, qhov kev faib hluav taws xob tsis zoo yog qhov tseem ceeb tshaj plaws. Ntawm no, ob lub resistors R1 thiab R2 yog ua haujlwm, uas txuas nrog VCC thiab muab kev tsis ncaj ncees. Lub resistor RE ua haujlwm nyob rau hauv lub emitter muab stabilization.
Puas yog tus kheej tsis ncaj ncees thiab qhov sib faib hluav taws xob tsis zoo ib yam?
Ib qhov tsis kam RE tau txuas nrog hauv lub emitter circuit. Cov resistor no tsis muaj nyob rau hauv qhov kev sib tw ruaj khov lossis cov khoom sib dhos rau lub hauv paus bias circuit. … Bias stabilization siv voltage divider bias circuit. Yog tias Ic nce vim qhov hloov pauv hauv qhov kub lossis βdc.
Dab tsi yog hom kev tsis ncaj ncees?
Qee yam ntawm txoj kev siv los muab kev tsis ncaj ncees rau lub transistor yog:
- Puas Kev Ncaj Ncees lossis Kev Ncaj Ncees Tam Sim No. …
- Base Bias nrog Emitter Cov Lus Qhia. …
- Base Bias nrog Sau Cov Lus Qhia. …
- Base Bias nrog Tus Sau Thiab Emitter Cov Lus Qhia. …
- Kev tsis ncaj ncees nrog ob yam khoom siv. …
- Voltage Divider Bias. …
- Input Impedance. …
- Output Impedance.
Vim li cas qhov kev faib hluav taws xob tsis zoo yog qhov nyiam?
Ntawm no yog qhov sib txawv ntawm cov emitter transistor configuration yog biased siv lub voltage divider network kom nce stability . … Qhov no voltage divider biasing configuration yog feem ntau siv transistor biasing txoj kev. Lub emitter diode ntawm lub transistor yog pem hauv ntej biased los ntawm tus nqi voltage tsimhla resistor RB2.
Peb hom kev tsis ncaj ncees yog dab tsi?
Peb hom kev tsis ncaj ncees tuaj yeem paub qhov txawv: qhia kev tsis ncaj ncees, kev xaiv tsis ncaj ncees, thiab tsis meej pem. Peb hom kev tsis ncaj ncees no thiab lawv cov kev daws teeb meem tau tham txog siv ntau yam piv txwv.
