Isingeniso somkhiqizo

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 "zesekethe ye-amplifier yomthombo" kanye "nesekhethi ye-drain amplifier", ezibukwayo ezihlobene nendlela yamanje yokugeleza ye-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 yokukhipha uhlobo lokuphumayo.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.
