Ingaruka Yumwanya Transistor ahinnye nkukoBYINSHI.Hari ubwoko bubiri bwingenzi: guhuza imirima yingirakamaro hamwe nicyuma-oxyde semiconductor yumurima. MOSFET izwi kandi nka tristoriste unipolar hamwe nabenshi mubatwara bafite uruhare mumashanyarazi. Nibikoresho bigenzurwa na voltage. Bitewe no kwinjiza kwinshi kwinshi, urusaku ruke, gukoresha ingufu nke, nibindi biranga, bigatuma iba umunywanyi ukomeye kuri bipolar transistors na tristoriste.
I. Ibipimo nyamukuru bya MOSFET
1, ibipimo bya DC
Umuyoboro wuzuye wuzuye ushobora gusobanurwa nkumuyoboro wamazi uhuye nigihe voltage iri hagati y irembo nisoko ihwanye na zeru kandi n’umuvuduko uri hagati y’amazi n’isoko urenze voltage ya pinch-off.
Pinch-off voltage UP: UGS isabwa kugabanya indangamuntu kumuyoboro muto mugihe UDS ari runaka;
Kuzimya voltage UT: UGS isabwa kuzana indangamuntu kugiciro runaka mugihe UDS ari runaka.
2 、 Ibipimo bya AC
Gm: Umuyoboro muke gm: Dondora ingaruka zo kugenzura irembo nisoko ya voltage kumashanyarazi.
Ubushobozi bwa inter-pole: ubushobozi hagati ya electrode eshatu za MOSFET, agaciro gake, niko gukora neza.
3 、 Kugabanya ibipimo
Umuyoboro, inkomoko yamenetse ya voltage: mugihe imiyoboro yamazi yazamutse cyane, izabyara avalanche mugihe UDS.
Irembo ryo kumenagura amarembo: guhuza ibikorwa byumurongo wibikorwa bisanzwe, irembo nisoko hagati ya PN ihuza muburyo bubogamye, ikigezweho ni kinini cyane kuburyo kidashobora gusenyuka.
II. IbirangaMOSFETS
MOSFET ifite imikorere ya amplification kandi irashobora gukora uruziga rwongerewe. Ugereranije na triode, ifite ibiranga bikurikira.
(1) MOSFET ni igikoresho kigenzurwa na voltage, kandi ubushobozi bugenzurwa na UGS;
(2) Ibiriho byinjira muri MOSFET ni bito cyane, bityo ibyinjira byinjira ni byinshi cyane;
(3) Ubushyuhe bwabwo ni bwiza kuko bukoresha ubwinshi bwabatwara ibintu;
.
(5) Irwanya cyane imirasire.
Icya gatatu,BYINSHI kugereranya transistor
.
. triode nigikoresho kiyobowe na voltage igikoresho, ubushobozi bwa amplification burakomeye.
(3) Irembo RYINSHI ahanini ntirifata ikigezweho; na triode akazi, shingiro izakuramo icyerekezo runaka. Kubwibyo, MOSFET yinjirira irwanya iruta triode yinjira.
. ifite ubushyuhe bwiza kandi irwanya imirasire kuruta transistor. MOSFET igomba guhitamo mugihe ibidukikije bihindutse cyane.
. yagabanutse.
(6) Igishusho cyurusaku rwa MOSFET ni gito.
. igipimo cyuzuzanya.
