Qhov tshwj xeeb ntawm cov khoom siv hluav taws xob qhib hluav taws xob hluav taws xob (OC rooj vag) ntawm NPN thiab PNP: kev hloov pauv cov zis ntawm saturation amplification.

Qhib collector yog ib daim ntawv thov tshwj xeeb ntawm triode amplifier circuit.Tus sau ntawm C yog teem rau theem siab, thiab lub emitter ntawm E yog teem rau theem qis.Thaum lub hauv paus ntawm B xa ib lub teeb liab me me, lub saturated amplified switching signal yog tso tawm ntawm lub collector, uas yog "1" nyob rau hauv digital circuit.Qhib collector amplifier Circuit Court yog qee zaum hu ua OC rooj vag.

Hauv kev lag luam automation, "PNP" thiab "NPN" tau hais ncaj qha raws li cov teeb liab tso tawm ntawm PNP qhib cov khoom siv hluav taws xob thiab cov zis ntawm NPN qhib collector amplifier circuit.

Lub davhlau ya nyob twg ntawm cov khoom siv hluav taws xob thiab cov teeb liab ntawm PNP qhib collector yog nyob rau theem qis, uas tseem hu ua hom cathode.

Lub hwj chim mov thiab teeb liab lub davhlau ya nyob twg ntawm NPN qhib collector yog nyob rau theem siab, uas tseem hu ua ntau anode.

Vim qhov sib txawv ntawm cov teeb liab ntws kev taw qhia thiab hom kev sib txuas ntawm cov davhlau ya nyob twg, PNP teeb liab thiab NPN teeb liab yuav tsum sib phim lub polarity ntawm qhov sib txuas tau txais Circuit Court, uas yog, PNP txais Circuit Court tau txais PNP teeb liab thiab NPN txais Circuit Court tau txais NPN teeb liab.

Hom hom thiab ntws hom yog cov ntawv luv ntawm "qhov chaw amplifier circuit" thiab "drain amplifier circuit", uas yog qhov pom kev txheeb ze rau cov kev taw qhia ntws tam sim no ntawm lub teeb liab amplifier.

Lub triode qhib collector circuit xa ib lub teeb liab me me, uas yog amplified mus rau ib tug switching teeb liab yuav tsum tau tso zis ntawm lub collector, uas yog zoo ib yam nrog lub sensor sensing lub cev teeb liab thiab ces outputting ib tug switching teeb liab.Yog li ntawd, ntau lub sensors xaiv hom NPN thiab PNP qhib cov khoom tso tawm hom.Lub pulse tso zis ntawm incremental encoder kuj yog ib qho kev hloov ntawm siab thiab qis theem mem tes, yog li muaj ntau yam incremental encoders tau xaiv qhov qhib collector tso zis hom NPN thiab PNP.
