Tus yam ntxwv thim rov qab yog kev sib txheeb ntawm qhov voltage thiab tam sim no thaum lub diode rov qab-cuam tshuam. Qhov rov qab hluav taws xob ua kom muaj zog tiv thaiv kev tiv thaiv ntawm cov hluav taws xob sab hauv mus rau lub diffusion ntawm ntau cov tub.
Ntau tus tub tuaj yeem nyuaj rau kev tawm tsam tam sim no, tab sis cov tub hluas cov tub rog feem ntau drift nyob rau hauv qhov kev ua ntawm hluav taws xob teb thiab tsim qhov txav me me tam sim no, uas yog qhov ywj pheej ntawm qhov ntau ntawm qhov hloov hluav taws xob.
Cov thim rov qab tam sim no nyob rau lub sijhawm no hu ua qhov kev hloov pauv rov qab tam sim no, thiab lub diode nthuav tawm qhov hloov siab heev thiab yog nyob rau hauv ib qho kev tsis txaus siab.
