Coupling capacitor yog cov khoom tseem ceeb hauv amplifier circuits. Lawv tau siv los tiv thaiv kev cuam tshuam ntawm transistor qhov tsis zoo ntawm qhov hluav taws xob los ntawm AC cov cimHauv cov amplifier circuits feem ntau, qhov no tau ua tiav los ntawm kev tsav lub teeb liab mus rau lub hauv paus davhlau ya nyob twg ntawm lub transistor los ntawm lub coupling capacitor.
Capacitor txuas yog dab tsi?
Coupling capacitors (los yog dc thaiv cov capacitors) yog siv rau decouple ac thiab dc signalsthiaj li tsis txhob cuam tshuam qhov quiescent point ntawm Circuit Court thaum ac signals raug txhaj ntawm lub tswv yim. Bypass capacitors yog siv los yuam cov teeb liab tam sim no nyob ib ncig ntawm cov khoom los ntawm kev muab txoj hauv kev qis impedance ntawm zaus.
Dab tsi yog capacitors siv rau hauv amplifiers?
Capacitors khoom hluav taws xob raws li lub zog tam sim no muaj rau koj lub tshuab hluav taws xob Yog tias lub tshuab hluav taws xob rub tawm tam sim no ntau dua li muaj los ntawm cov hluav taws xob ncaj qha, lub capacitor npog qhov sib txawv mus txog nws lub peev xwm khaws cia. Lub roj teeb tsis yog overloaded thiab lub tsheb voltage nyob ruaj khov.
Vim li cas lub coupling capacitor siv nyob nruab nrab ntawm theem ntawm lub tshuab hluav taws xob?
Coupling Capacitor C
Cov capacitor CC yog lub coupling capacitor uas txuas ob theem thiab tiv thaiv DC cuam tshuam ntawm cov theem thiab tswj qhov chaw ua haujlwm los ntawm shifting Qhov no tseem hu ua blocking capacitor vim nws tsis tso cai rau DC voltage hla nws.
Lub hom phiaj ntawm cov capacitors hauv lub amplifier transistor yog dab tsi?
Yog hais tias lub bypass capacitor raug tshem tawm, qhov degeneration heev yog tsim nyob rau hauv amplifier Circuit Court thiab qhov voltage tau txais yuav raug txo. Yog li, lub hom phiaj ib leeg lossis lub luag haujlwm ntawm lub emitter capacitor yog kom tsis txhob muaj qhov nce siab poob.
