Kukhazikika kwa dera lotseguka la amplifier amplifier (OC chipata) cha NPN ndi PNP: kusintha kosinthika kwa machulukitsidwe amplifier.

Open collector ndi ntchito yapadera ya triode amplifier circuit. Wosonkhanitsa C amayikidwa pamlingo wapamwamba, ndipo emitter ya E imayikidwa pamlingo wochepa. Chitsimikizo cha B chikatumiza chizindikiro chaching'ono, chizindikiro chosinthira chokhazikika chimatuluka pa osonkhanitsa, chomwe ndi "1" mumayendedwe a digito. Open collector amplifier circuit nthawi zina amatchedwa OC chipata.

M'makampani opanga makina, "PNP" ndi "NPN" adawonetsedwa mwachindunji ngati mawonekedwe amtundu wa PNP otsegulira amplifier ndi kutulutsa kwa NPN otsegulira amplifier dera.

Malo odziwika bwino a magetsi ndi chizindikiro cha PNP chosonkhanitsa chotseguka chili pamunsi, chomwe chimatchedwanso cathode wamba.

Magetsi ndi ma sign terminal a NPN open collector ali pamlingo wapamwamba, womwe umatchedwanso common anode.

Chifukwa cha kusiyana kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.

Mtundu wa magwero ndi mtundu wa drain ndizochidule cha "source amplifier circuit" ndi "drain amplifier circuit", zomwe zimawoneka zogwirizana ndi njira yomwe ikuyenderera ma sign amplifier.

Dongosolo la osonkhanitsa lotseguka la triode limatumiza chizindikiro chaching'ono, chomwe chimakulitsidwa ku siginecha yosinthira kuti itulutsidwe kwa osonkhanitsa, zomwe zimagwirizana ndi sensa yomwe imamva chizindikiro chakuthupi ndikutulutsa chizindikiro chosinthira. Chifukwa chake, masensa ambiri amasankha mtundu uwu wa NPN ndi PNP otseguka okhometsa mtundu. Kutulutsa kwa pulse kwa incremental encoder ndikusinthanso kwamphamvu komanso kutsika kwapang'onopang'ono, kotero ma encoder ambiri oyambilira adasankhanso mtundu uwu wa NPN ndi PNP.
