PNP thiab NPN hloov cov cim ntawm lub sensor (1)

Lub PNP thiab NPN hloov cov teeb liab ntawm lub sensor yog ob hom kev hloov pauv sensor tso tawm cov teeb liab pom tau los ntawm kev siv cov saturation (conduction) thiab txiav tawm (disconnection) ntawm PNP thiab NPN transistors hauv cov zis hluav taws xob ntawm lub sensor.

Vim muaj cov yam ntxwv sib txawv ntawm cov khoom siv hluav taws xob ntawm PNP thiab NPN transistors, qhov hloov pauv cov cim tso tawm los ntawm lawv yog diametrically tawm tsam, uas feem ntau hu ua qib siab thiab qib qis.

Rau kev hloov pauv, nws tsis yog qhov nyuaj rau peb kom nkag siab tias nws txoj haujlwm yog kev coj ua (tsim hu ua qhov hloov pauv hauv lub xeev kaw (Clos)), lossis txiav tawm (tsim hu ua qhib (Qhib) xeev). Ntawd yog hais tias, qhov tshwm sim ntawm cov neeg ua haujlwm hloov pauv raws li lub hom phiaj ntawm kev thov sib txawv yog hloov lub xeev ntawm kev hloov.
