Imininingwane yesekethe ye-amplifier yomqoqi ovulekile (isango le-OC) le-NPN ne-PNP: ukukhishwa kokushintshwa kokukhulisa ukugcwaliswa kwesikhala.
Umqoqi ovulekile uhlelo lokusebenza olukhethekile lwesekethe ye-amplifier ye-triode. Umqoqi we-C usethelwe ezingeni eliphezulu, futhi i-emitter ye-E isethwe ezingeni eliphansi. Uma isisekelo sika-B sithumela isignali encane, isignali yokushintsha egxilisiwe egcwele iphuma kumqoqi, okungukuthi "1" kumjikelezo wedijithali. Isekethe ye-amplifier yokuqoqa evulekile kwesinye isikhathi ibizwa ngesango le-OC.
Embonini ye-automation, "i-PNP" ne-"NPN" kuvezwe ngokuqondile njengokuphuma kwesiginali yesekethe ye-PNP evulekile yomqoqi we-amplifier kanye nokukhishwa kwesekethe ye-NPN yomqoqi ovulekile we-amplifier.
Itheminali evamile yokunikezwa kwamandla kanye nesignali ye-PNP evulekile yokuqoqa isezingeni eliphansi, elibizwa nangokuthi i-cathode evamile.
Ukunikezwa kwamandla kanye netheminali evamile yesignali yomqoqi ovulekile we-NPN kusezingeni eliphezulu, elibizwa nangokuthi i-anode evamile.
Ngenxa yomehluko wesiqondiso sokugeleza kwesignali kanye nemodi evamile yokuxhumana yesiphetho, isignali ye-PNP nesignali ye-NPN kufanele futhi ifane ne-polarity yesifunda sokwamukela esihambisanayo, okungukuthi, i-PNP yokwamukela isifunda ithola isignali ye-PNP futhi i-NPN ethola isifunda ithola isignali ye-NPN.
Uhlobo lomthombo kanye nohlobo lokudonsa amanzi izifinyezo "zesekhethi yomthombo we-amplifier" kanye "nesekhethi ye-drain amplifier", okubonakalayo okuhlobene nesiqondiso sokugeleza kwamanje kwe-amplifier yesignali.
Isekhethi yeqoqo elivulekile le-triode ithumela isignali encane, ekhuliswa kusignali yokushintsha ukuze ikhishwe kumqoqi, ehambisana nenzwa ezwa isignali ebonakalayo bese ikhipha isignali yokushintsha. Ngakho-ke, izinzwa eziningi zikhetha lolu hlobo lwe-NPN ne-PNP evulekile yohlobo lokuphumayo lomqoqi. Ukukhishwa kwe-pulse yesishumeki sekhodi esikhuphukayo nakho kuwushintsho lwezinga eliphezulu neliphansi lokushaya kwenhliziyo, ngakho-ke izifaki khodi eziningi zangaphambi kwesikhathi nazo zikhethe lolu hlobo lokuphumayo lomqoqi ovulekile lwe-NPN ne-PNP.
