ʻO ka pilina ma waena o MOSFET a me nā Transistors Field Effect

Ua loaʻa ka ʻoihana ʻenehana uila i kahi e kū nei me ke kōkua ʻole oMOSFETa me nā transistors hopena kahua. Eia nō naʻe, no kekahi poʻe hou i ka ʻoihana uila, maʻalahi pinepine ka huikau MOSFET a me nā transistors hopena kahua. He aha ka pilina ma hope o MOSFET a me nā transistors hopena kahua?

ʻOiaʻiʻo, e like me ka hoʻokomo ʻana o kēia mau mea uila, ʻōlelo ʻo MOSFET ʻo ka transistor hopena kahua ʻaʻole pilikia, akā ʻaʻole pololei ka ʻaoʻao ʻē aʻe, ʻo ia hoʻi, ʻo ka transistor hopena kahua ʻaʻole wale nō me MOSFET, akā pū kekahi. nā mea uila ʻē aʻe.

Hiki ke hoʻokaʻawale ʻia nā transistors hopena kahua i nā paipu hui a me nā MOSFET. Hoʻohālikelike ʻia me MOSFET, hoʻohana ʻia nā paipu hui, no laila he haʻahaʻa loa ke alapine o ka haʻi ʻana i nā paipu hui, a ʻōlelo pinepine ʻia nā MOSFET a me nā transistors hopena kahua, no laila ua maʻalahi ka hoʻomaopopo ʻana he ʻano like lākou.

MOSFETHiki ke hoʻokaʻawale ʻia i ke ʻano hoʻonui a me ke ʻano depletion, ʻokoʻa iki ke kumu hana o kēia mau mea uila ʻelua, ʻano paipu hoʻonui i ka puka (G) me ka volta maikaʻi, ka wai (D) a me ke kumu (S) i mea e hana, ʻoiai ke ʻano hoʻohaʻahaʻa inā ʻaʻole i hoʻohui ʻia ka puka (G) i ka volta maikaʻi, ʻo ke kahawai (D) a me ke kumu (S) he conductive pū kekahi.

Maanei ʻaʻole i pau ka hoʻokaʻawale ʻana o ka transistor hopena kahua, hiki ke hoʻokaʻawale ʻia kēlā me kēia ʻano o ka paipu i nā paipu N-type a me nā ʻano P-type, no laila hiki ke hoʻokaʻawale ʻia ka transistor hopena kahua i ʻeono mau ʻano paipu ma lalo, kēlā me kēia, N-channel. nā transistors hopena kahua hoʻohui, nā transistors hopena kahua pānaʻi hui ʻana, nā transistors hopena kahua hoʻonui ʻia N-kanal, nā transistors hopena kahua hoʻonui ʻia P-kanal, nā hopena kahua hoʻopau N-kanela. transistors, a me P-channel depletion type Field Effect Transistors.

He ʻokoʻa kēlā me kēia ʻāpana o ke kiʻikuhi kaapuni o nā hōʻailona kaapuni, no ka laʻana, ke hōʻike nei ke kiʻi ma lalo nei i nā hōʻailona kaapuni o nā ʻano paipu hui ʻelua, ʻo ka pua pine Helu 2 e kuhikuhi ana i ka paipu no ka transistor hopena kahua hui N-channel. , e kuhikuhi ana i waho ka P-channel junction field effect transistor.

MOSFETa me ka junction tube kaapuni hōʻailona ʻokoʻa ʻokoʻa ka nui, N-channel depletion type field effect transistor a me P-channel depletion type field effect transistor, ka pua like e kuhikuhi ana i ka paipu no ka N-type, e kuhikuhi ana i waho ka P-type tube. . Pēlā nō, ʻo ka ʻokoʻa ma waena o ka N-channel enhancement type field effect transistors a me P-channel enhancement type field effect transistors ma muli o ke kuhikuhi ʻana o ka pua, ʻo ke kuhikuhi ʻana i ka paipu he N-type, a ʻo ke kuhikuhi ʻana i waho he P-type.

ʻO nā transistors hopena kahua hoʻonui (me ka paipu N-type a me ka paipu P-type) a me nā transistors hopena kahua hoʻopau (me ka paipu N-type a me ka paipu P-type) kokoke loa. ʻO ka ʻokoʻa ma waena o nā mea ʻelua, ʻo ia ka hōʻike ʻana o kekahi o nā hōʻailona e kahi laina kaha ʻia a ʻo kekahi me kahi laina paʻa. Hōʻike ka laina kiko i kahi transistor hopena kahua hoʻonui a hōʻike ka laina paʻa i kahi transistor hopena hopena.
