Nyob rau hauv tus qauv diode, rau pem hauv ntej biasing tshwm sim thaum qhov hluav taws xob hla ib lub diode tso cai rau lub ntuj ntws ntawm tam sim no, whereas reverse biasing denotes ib voltage hla lub diode nyob rau hauv opposite direction.
Yuav ua li cas rau pem hauv ntej thiab thim rov qab?
A diode (PN junction) nyob rau hauv ib qho hluav taws xob Circuit Court tso cai rau tam sim no ntws yooj yim dua nyob rau hauv ib qho kev taw qhia dua lwm yam. Forward biasing txhais tau tias muab qhov hluav taws xob hla lub diode uas tso cai rau tam sim no ntws tau yooj yim, thaum rov qab biasing txhais tau tias muab qhov hluav taws xob hla lub diode nyob rau sab nraud.
Dab tsi yog qhov txawv ntawm pem hauv ntej thiab thim rov qab?
Kev thim rov qab ua kom lub diode tsis kam, thiab kev tsis ncaj ncees rau pem hauv ntej txo qhov diode tsis kam. Ib qho kev thim rov qab tsis tso cai rau qhov tam sim no ntws, qhov uas nws ntws mus rau hauv kev tsis ncaj ncees rau pem hauv ntej los ntawm diode.
txhais li cas los ntawm kev thim rov qab?
reverse bias Kev siv d.c. qhov hluav taws xob uas tiv thaiv lossis txo qis tam sim no hauv diode, transistor, thiab lwm yam. Piv txwv li, qhov tsis txaus ntseeg tam sim no yuav ntws los ntawm lub diode thaum nws cov cathode ua tau zoo dua li nws cov anode; Tom qab ntawd lub diode tau hais kom rov qab biased. Sib piv rau pem hauv ntej kev tsis ncaj ncees.
Yuav ua li cas rau pem hauv ntej kev tsis ncaj ncees piv txwv?
kev tsis ncaj ncees The d.c. voltage yuav tsum tau tswj xyuas tam sim no ntws nyob rau hauv ib tug bipolar transistor los yog diode los yog txhim khu tam sim no txaus nyob rau hauv lub teb-zoo transistor. Piv txwv li, silicon diode yuav ua tam sim no tsuas yog tias nws cov anode nyob ntawm qhov zoo voltage piv rau nws cov cathode; ces yog hais rau pem hauv ntej biased.
