Binciken siga da aunawar MOSFETs

Akwai nau'ikan manyan sigogi da yawa naMOSFET, wanda ya ƙunshi DC halin yanzu, AC halin yanzu sigogi da iyaka sigogi, amma general aikace-aikace kawai bukatar kula da wadannan asali sigogi: jikewa yanayin da yayyo tushen halin yanzu IDSS tsunkule-kashe ƙarfin lantarki Up, transconductance gm, yayyo tushen rushewar ƙarfin lantarki BUDS, mafi girman ƙarfin fitarwar asara PDSM da babban tushen yabo IDSM na yanzu.

1.Saturated leakage source current

Cikakkun tushen magudanar ruwa na yanzu IDSS yana nufin magudanar ruwa-tushen halin yanzu a ƙarfin lantarki na ƙofar UGS = 0 a cikin junction ko nau'in ƙofa mai rufi MOSFETs.

2. Clip-kashe ƙarfin lantarki

Ƙunƙasa-kashe ƙarfin lantarki UP yana nufin ƙarfin wutar lantarki mai aiki a ƙofar kofa a cikin junction ko nau'in nau'in lalacewa mai rufi.MOSFETwannan ya sa tushen magudanar ruwa kawai ya yanke. Gano abin da IDSS da UP a zahiri suke nufi.

3. Kunna wutar lantarki

Wutar lantarki ta kunna UT tana nufin wutar lantarki mai aiki a ƙofar MOSFET mai insulated-ƙofa don kawai an kunna haɗin tushen magudanar ruwa. Gano abin da UT ke nufi a zahiri.

4.Cross-shiriya

Ana amfani da transguide gm don nuna ikon ƙarfin wutar lantarki na ƙofar ƙofar don sarrafa magudanar ruwa, wato, rabo tsakanin canjin magudanar ruwa da canjin wutar lantarki ta hanyar ƙofar.

5. Matsakaicin asarar ƙarfin fitarwar

Matsakaicin ikon fitar da asara shima yana cikin madaidaicin iyaka, wanda ke nufin matsakaicin ƙarfin asarar magudanar ruwa wanda za'a iya ba da izini lokacin aikinMOSFETal'ada ce kuma ba ta da tasiri. Lokacin da muke amfani da MOSFET, asarar aikin sa yakamata ya zama ƙasa da PDSM da wata ƙima.

6.Mafi girman yayyo tushen halin yanzu

Matsakaicin magudanar ruwa-tushen halin yanzu, IDSM, shine ma'auni mai iyakancewa, wanda ke nufin iyakar halin yanzu da aka bari ya wuce tsakanin magudanar ruwa da tushen MOSFET yayin aiki na yau da kullun, kuma dole ne a wuce lokacin da MOSFET ke aiki.

olukey ya zama ɗaya daga cikin wakilai mafi kyau kuma mafi sauri a cikin Asiya ta hanyar haɓaka kasuwa mai aiki da haɗin kai mai inganci, kuma zama wakili mafi mahimmanci a duniya shine manufa gama gari na olukey.
