Izimfanelo Zomkhiqizo

Baba khona kanjani abaholi abaphezulu be-analog abayi-10 emhlabeni?

Kuwo wonke umlando, abaholi be-analog chip bakhule besuka ezimakethe ezinkulu.I-China, okwamanje inemakethe enkulu ye-semiconductor kanye nezinga eliphezulu lokukhula, kulindeleke ukuthi iphindaphinde izimo eziholele ekukhuleni okusheshayo kwe-ADENO.

Umthombo wayo yonke idatha isignali ye-analog, futhi ama-analog chips ayiziyingi ze-analog ezihlanganisiwe zokucubungula amasignali e-analog.Amasignali e-analogi amasignali aqhubekayo ngesikhathi nobukhulu, kuyilapho amasignali edijithali angamasiginali angaqhubeki ngesikhathi nobukhulu.Ngemva kokuba isignali yangaphandle iguqulelwe inzwa ibe isignali kagesi, iyisignali ye-analog ethuthukiswa ngokwengeziwe futhi ihlungwe ohlelweni oluhlanganisa chip ye-analog.Isiginali ye-analogi ecutshunguliwe ingakhishelwa kusistimu yedijithali ukuze icutshungulwe ngesiguquli sedatha noma ngokuqondile ku-actuator.

Amasistimu ahlanganisiwe ajwayelekile edijithali-kuya-analog ahlanganisa omakhalekhukhwini, amakhompyutha omuntu siqu, amakhamera edijithali, imibhobho, nezipikha, njll. emkhakheni wabathengi, izitholi zokushisa, ama-electrocardiographs, amasistimu ezindiza emkhakheni wezimboni, ukubuyisela emuva izibonisi emkhakheni wezimoto, njll. . Ama-analogue chips atholakala yonke indawo.

Amasignali adluliselwa ngendlela kagesi futhi ahlukaniswe abe izinhlobo ezimbili zezimpawu ze-analog, ezibuthakathaka neziqinile, kuye ngokuthi amandla amanje / amandla kagesi.Imikhiqizo yochungechunge lwesignali inesibopho sokucubungula amandla abuthakathaka.Imikhiqizo yokuphatha amandla ibhekene ikakhulukazi nokucubungula amandla aqinile, kodwa futhi namandla abuthakathaka.

Indawo yemakethe ye-analog chip yomhlaba wonke icishe ibe yizigidi eziyizinkulungwane ezingama-US $60.Imakethe yomhlaba wonke yamasekethe ahlanganisiwe ingu-USD 340.2 bhiliyoni, kanti amasekethe e-analog alinganiselwa ku-15%.Kumasekhethi e-analog, imakethe ye-signal chain ingama-dollar ayizigidi eziyizinkulungwane eziyi-14.3, kanti imakethe yokuphatha amandla ingama-dollar ayizigidi eziyizinkulungwane ezingama-21.6.Kusukela nge-op-amp yokuqala edidiyelwe eyavela ngo-1968, ngo-2018, ama-analog chips asephenduke imboni yomhlaba wonke ecishe ibe yizigidi eziyizinkulungwane ezingama-US $60.

Njengamanje, izinkampani eziyishumi eziphezulu ze-analog chip zinengxenye engaphezu kwengxenye yesabelo semakethe.Ngo-2018, izinkampani eziyishumi eziphezulu ze-analog chip kwakuyi-Texas Instruments (TI), i-Adenor (ADI), i-Infineon, i-Skyworks, i-ST Microelectronics, i-NXP, i-Maxim, i-On Semiconductor, ne-On Semiconductor.I-Maxim, i-On Semi, i-Microchip, ne-Renesas.

Phakathi kwabo, i-Texas Instruments igxile ekuphathweni kwamandla futhi ingumholi kulo mkhakha;I-ADI iqale ngama-amplifiers asebenzayo futhi ingumholi kuziguquli zedatha, enesabelo semakethe esiphezulu kuma-op-amps nokuphathwa kwamandla.U-Infineon ukhishwe kuSiemens Group futhi uyinkampani esohlwini oluzimele lwe-semiconductor.Izinkampani zamanje ezisezingeni eliphezulu ze-analog chip, ezasungulwa ekuqaleni kwawo-1960 kanye neminyaka yawo-1990 lapho kuzalwa amasekethe ahlanganisiwe, zakhula kanye nemboni yesifunda edidiyelwe, okuhlanganisa nomholi wamanje iTexas Instruments (1930), owayengumholi weNational Semiconductor. (1959), kanye nendawo yesibili yamanje i-Adenor (1965), ethembele ekuqoqweni kwasekuqaleni kobuchwepheshe be-analog (Know-how) ukwakha amakhono angu-Core.

Umholi usekude kakhulu ezigabeni ezahlukahlukene zemakethe ye-analog chip

Phakathi kwama-IC analogi, ukuphathwa kwamandla kuyimakethe enkulu kunazo zonke enosayizi olinganiselwa ku-US$21.6 billion noma u-42%;imakethe ye-signal chain ingama-US$14.3 billion (28%) kanti i-RF kanye neminye imakethe yemikhiqizo ilinganiselwa ku-US$15.8 billion noma 30%.Engxenyeni ye-amplifier, i-Texas Instruments iphethe cishe ingxenye yesithathu yemakethe (29%), ne-ADENO yesibili (18%).Esigabeni sokuguqula idatha, i-ADENO ingumholi ophelele, okwamanje ephethe ingxenye yemakethe yokuguqula idatha (48%) futhi inomholi wesikhathi eside phezu kwezimbangi zayo.Engxenyeni yokuphathwa kwamandla, umholi, i-Texas Instruments, iphethe ngaphezu kwekota yemakethe (21%), i-Qualcomm (15%), i-ADENO (13%), i-Mexico (12%), ne-Infineon (10%) ine amasheya afanayo.
