Dab tsi yog Transistor

Transistor lub npe tag nrho yuav tsum yog semiconductor transitor, tseem hu ua bipolar transistor, siv lead ua triode, yog ib qho khoom siv semiconductor uas tswj tam sim no. Nws txoj haujlwm yog txhawm rau nthuav tawm cov teeb liab tsis muaj zog rau hauv cov teeb liab hluav taws xob nrog cov amplitude loj, thiab nws kuj yog siv los ua qhov tsis sib cuag.

Transistor yog ib qho ntawm cov khoom siv hluav taws xob semiconductor, uas muaj kev ua haujlwm ntawm kev nthuav dav tam sim no thiab yog lub hauv paus tseem ceeb ntawm cov khoom siv hluav taws xob. Lub triode yog ua kom ob lub PN junctions ze rau ib leeg ntawm ib qho semiconductor substrate. Ob lub PN junctions faib tag nrho cov semiconductor rau hauv peb qhov chaw, qhov nruab nrab yog thaj chaw hauv paus, thiab ob sab yog thaj chaw emission thiab thaj chaw sau. Txoj kev npaj yog PNP thiab NPN.
