Kev piav qhia: Lub swamping resistor yog ib qho kev tsis sib haum xeeb nyob rau hauv lub emitter (re) circuit of a common-emitter amplifier. Lub swamping resistorstabilizes qhov nce voltage thiab txo qis distortion. … Cov txheej txheem no pab cais cov DC kev tsis ncaj ncees ntawm ob lub voj voog sib txuas.
Lub hom phiaj ntawm lub emitter capacitor nyob rau hauv ib qho emitter amplifier yog dab tsi?
Nyob rau hauv Common Emitter Amplifier circuits, capacitors C1 thiab C2 yog siv raws li Coupling Capacitors cais cov AC signals los ntawm DC biasing voltage.
Dab tsi yog cov emitter amplifier nrog degeneration?
BJT Common Emitter Amplifier nrog emitter degeneration
Emitter degeneration hais txog qhov sib ntxiv ntawm ib qho me me resistor (R4) nruab nrab ntawm cov emitter thiab cov teeb liab sib txawv. Nyob rau hauv lub voj voog no lub hauv paus davhlau ya nyob twg ntawm lub transistor yog cov tswv yim, lub collector yog cov zis, thiab cov emitter yog ib qho rau ob qho tib si.
Vim li cas peb thiaj siv emitter degeneration?
Los ntawm kev ntxig cov resistor hauv koob nrog cov emitter, peb "degenerate" theem CE. Qhov no topology yuav txo qhov nce ntawm lub amplifier tab sis • Qhov topology no yuav txo qhov nce ntawm amplifier tab sis txhim kho lwm yam, xws li linearity, thiab input impedance.
Dab tsi yog daim ntawv thov ntawm lub suab nrov nrov nrov?
Cov emitter Circuit Court yog nrov vim nws zoo haum rauvoltage amplification, tshwj xeeb tshaj yog nyob rau qis zaus. Common-emitter amplifiers kuj siv nyob rau hauv xov tooj cua zaus transceiver circuits. Common emitter configuration feem ntau siv nyob rau hauv lub suab qis amplifiers.
