Ko te transistor - te turanga o te hangarau Semiconductor

Transistor - he mema mo te amplification, whakatupuranga, a hoki hoki tahuri oscillations hiko. Ko o rua momo transistors: pourua me te mara.

transistor pourua - he pūrere Semiconductor arā, o rua PN Junctions. transistor Timatanga hangaia i runga i te karaihe germanium, kua reira e rua mārau: he kaituku me te kaikohi, e pā ana ki te mata karaihe, wehe i tetahi ki tetahi i te tawhiti o 20-50 microns. I roto i te mau parau te tahi atu, hono te ara hīkoi te kaituku ki te turanga (huaina te mea te huinga kaituku), me te tuarua - te kaikohi ki te turanga (huaina ai ko te huinga tango). E wehea transistors pourua ki e rua ngā momo: PnP me npn.

Ko te transistor pānga mara - he pūrere Semiconductor, te mana nei i ngā rerekētanga o te parae, i roto i te rerekē ki ngā āhuatanga pourua, te wahi takoto te nāianei putanga e huri i te nāianei tāuru. He odnozatvornymi me mnogozatvornymi pūrere mara.

whakaaturia hoahoa schematic o te transistor e i roto i te pikitia i raro nei. Scheme huānga pourua ko te pūtake rārangi-poto, tohu te reira i te turanga, i roto i nei i 60 ⁰ me 120 ⁰ ngā rua ngā rārangi hauroki, he aho ki he pere - ko te kaituku, te tuarua - te kaikohi. aronga o te pere tohu te momo o te taputapu. Pere tuhu ki te pātengi raraunga - tenei transistor PnP momo o te turanga - npn. Hāngai ki te rārangi turanga - he kawehiko turanga. Me ki mohio ki te hono tika te transistor ki te supply te mana te uara o te kawenga hiko o te kaituku. pato Taputapu PnP te kaikohi me he tika turanga ki te homai i te ngaohiko transistor me npn momo kino - pai. FETs e tohua i roto i te hoahoa e whai ake: kuwaha hanga he whakaatu pīhono, tohu hongere whakarara, te kawe ia o te awa fakafofonga'i e te pere whakanohoia i waenganui i te pūtake me te awakeri. Ki te nga ngā pere i roto i te ahunga o te awa, te auraa e te huānga no ki n-momo, me te mea i roto i te huarahi i te ritenga, ka te p-momo. Image o te transistor pānga mara ki te arataki hongere rerekē i roto i te toru whiu poto. Ki te he te pūrere mara e rave rahi kuwaha, ratou whakaatu pīhono poto, kua whakanohoia tonu te raina kuwaha tuatahi i runga i te toronga o te raina pūtake.

I roto i te mutunga, tāpiri tatou e o kahore e titi tonu te transistors te ingoa, i huaina tuatahi ratou triodes Semiconductor (hangarau ngongo rite). Na e te transistor - he transistor, i te mea he āhuatanga controllable, Kei te whānui whakamahia te reira i roto i te whakawhiti me te faananea- raa iahiko. Ko te kore o te kaha, tika, iti ngā āhuatanga me te utu - ko nga painga matua o enei whakaaro, e tika ana ki nei i taea e transistors peia i te manga maha o nga ngongo korehau toi enei. Ko te painga matua o ngā pūrere Semiconductor ko te kore o te pitoiho wera, e pau te mana nui, me te wa tango ki te whakamahana ake. I tua atu, he nui iti ake i te rama hiko te transistor me he taea ki te mahi i te ngaohiko o raro. Kua whakaaetia tenei katoa ki tino whakaiti i te rahi o ngā pūrere hiko.
