I-BFS481H6327 Izifunda Ezihlanganisiwe Zokulawula/Ukuphatha Izihlukanisi Eziphindaphindayo ze-Analog

Izimfanelo Zomkhiqizo

Izigaba Zemvelo Nokuthekelisa

I-transistor iyithuluzi le-semiconductor elivame ukusetshenziswa kuma-amplifiers noma amaswishi alawulwa ngogesi.Ama-Transistors amabhlokhi wokwakha ayisisekelo alawula ukusebenza kwamakhompuyutha, omakhalekhukhwini, nawo wonke amanye amasekhethi esimanje kagesi.

Ngenxa yesivinini sabo sokuphendula ngokushesha nokunemba okuphezulu, ama-transistors angasetshenziswa ezinhlobonhlobo zemisebenzi yedijithali neye-analog, okuhlanganisa ukukhulisa, ukushintsha, ukulawulwa kwamandla kagesi, ukuguquguquka kwesignali kanye ne-oscillator.Ama-Transistors angapakishwa ngawodwana noma endaweni encane kakhulu engabamba ama-transistors ayizigidi eziyi-100 noma ngaphezulu njengengxenye yesekethe ehlanganisiwe.

Uma kuqhathaniswa neshubhu le-electron, i-transistor inezinzuzo eziningi:

I-1.Ingxenye ayinakho ukusetshenziswa

Kungakhathaliseki ukuthi ishubhu lihle kangakanani, lizowohloka kancane kancane ngenxa yezinguquko kuma-athomu e-cathode kanye nokuvuza komoya okungapheli.Ngenxa yezizathu zobuchwepheshe, ama-transistors ayenenkinga efanayo lapho enziwa okokuqala.Ngokuthuthuka kwezinto zokwakha kanye nokuthuthukiswa kwezici eziningi, ama-transistors ahlala isikhathi eside izikhathi eziyi-100 kuye kweziyi-1,000 kunamashubhu kagesi.

2.Sebenzisa amandla amancane kakhulu

Kuyingxenye eyodwa kweshumi noma amashumi eyodwa kuphela electron tube.Akudingi ukushisa i-filament ukukhiqiza ama-electron mahhala njengeshubhu le-electron.Umsakazo we-transistor udinga kuphela amabhethri omile ambalwa ukuze ulalele izinyanga eziyisithupha ngonyaka, okunzima ukuwenza kumsakazo weshubhu.

3.Asikho isidingo sokushisa kuqala

Sebenza ngokushesha nje lapho uyivula.Ngokwesibonelo, umsakazo we-transistor uyacima ngokushesha nje lapho uvulwa, futhi ithelevishini ye-transistor imisa isithombe ngokushesha nje lapho ivulwa.Imishini ye-vacuum tube ayikwazi ukwenza lokho.Ngemuva kwe-boot, linda isikhashana ukuze uzwe umsindo, ubone isithombe.Ngokusobala, kwezempi, ukulinganisa, ukuqopha, njll., ama-transistors anenzuzo kakhulu.

4.Eqinile futhi enokwethenjelwa

Izikhathi eziyi-100 ezinokwethenjelwa kakhulu kuneshubhu le-electron, ukumelana nokushaqeka, ukumelana nokudlidliza, okungenakuqhathaniswa neshubhu le-electron.Ukwengeza, ubukhulu be-transistor buyingxenye eyodwa kweshumi kuya kwekhulu kuphela yobukhulu beshubhu ye-electron, ukukhululwa okuncane kakhulu kokushisa, kungasetshenziswa ukuklama izifunda ezincane, eziyinkimbinkimbi, ezinokwethenjelwa.Nakuba inqubo yokukhiqiza i-transistor inembile, le nqubo ilula, esiza ekuthuthukiseni ukuminyana kokufakwa kwezingxenye.
