Iimpawu zeMveliso

Zenzeke njani iinkokeli ezili-10 zehlabathi ze-analog?

Kuyo yonke imbali, iinkokeli ze-analog chip ziye zakhula kwiimarike ezinkulu.I-China, okwangoku ineemakethe ezinkulu ze-semiconductor kunye nezinga eliphezulu lokukhula, kulindeleke ukuba liphindaphinde iimeko ezikhokelela ekukhuleni ngokukhawuleza kwe-ADENO.

Umthombo wayo yonke idatha ngumqondiso we-analog, kwaye iichips ze-analog zihlanganisiweyo zeesekethe ze-analog zokusetyenzwa kweempawu ze-analog.Iimpawu ze-analog zizibonakaliso eziqhubekayo ngexesha kunye nobukhulu, ngelixa iimpawu zedijithali ziyimpawu eziye zayeka ngexesha kunye nobukhulu.Emva kokuba isignali yangaphandle iguqulwe yinzwa ibe ngumqondiso wombane, ngumqondiso we-analog oye wandiswa ngakumbi kwaye wahluzwa kwinkqubo equkethe i-analog chip.Isignali ye-analog esetyenzisiweyo inokuba yimveliso kwi-digital system ukuze iqhutywe nge-converter yedatha okanye ngokuthe ngqo kwi-actuator.

Iinkqubo eziqhelekileyo ze-digital-to-analog hybrid zibandakanya iifowuni eziphathwayo, iikhomputha zomntu, iikhamera zedijithali, ii-microphone, kunye nezithethi, njl njl. kwicandelo labathengi, i-detectors yeqondo lokushisa, i-electrocardiographs, iinkqubo zeenqwelo-moya kwicandelo loshishino, ukubuyisela umva iziboniso kwicandelo lezemoto, njl. Iitshiphusi ze-analog zikho kuyo yonke indawo.

Iimpawu zihanjiswa ngendlela yombane kwaye zihlukaniswe zibe zimbini iintlobo zeempawu ze-analog, zibuthathaka kwaye zinamandla, kuxhomekeke kumandla akhoyo / i-voltage.Iimveliso zekhonkco lomqondiso zinoxanduva lokucubungula amandla abuthathaka.Iimveliso zolawulo lwamandla zinoxanduva ikakhulu lokusetyenzwa kwamandla awomeleleyo, kodwa namandla abuthathaka.

Indawo yemarike ye-analog yehlabathi iphantse yangama-60 eebhiliyoni zeedola.Imarike yehlabathi yeesekethe ezihlanganisiweyo yi-USD 340.2 yebhiliyoni, kunye neesekethe ze-analog ezibalelwa kwi-15%.Kwimijikelezo ye-analog, imakethi ye-signal chain yi-US $ 14.3 yezigidigidi, kwaye imarike yolawulo lwamandla yi-US $ 21.6 yezigidigidi.Ukuqala nge-op-amp yokuqala edibeneyo eyavela kwi-1968, ngo-2018, iitshiphusi ze-analog ziye zaba lishishini lehlabathi malunga ne-US $ 60 yebhiliyoni.

Okwangoku, iinkampani eziphezulu ze-analog chip ze-10 zibamba ngaphezu kwesiqingatha sesabelo semarike.Kwi-2018, iinkampani eziphezulu ze-10 ze-analog chip zaziyi-Texas Instruments (TI), i-Adenor (ADI), i-Infineon, i-Skyworks, i-ST Microelectronics, i-NXP, i-Maxim, i-On Semiconductor, kunye ne-On Semiconductor.Maxim, On Semi, Microchip, kunye Renesas.

Phakathi kwabo, i-Texas Instruments igxile kulawulo lwamandla kwaye iyinkokeli kulo mmandla;I-ADI yaqala ngama-amplifiers asebenzayo kwaye iyinkokeli ekuguquleni idatha, kunye nesabelo esiphezulu semarike kwi-op-amps kunye nolawulo lwamandla.I-Infineon yakhutshwa kwiQela le-Siemens kwaye iyinkampani edweliswe ngokuzimeleyo ye-semiconductor.Iinkampani zangoku ezikwinqanaba eliphezulu le-analog chip, ezasekwa ekuqaleni kweminyaka yoo-1960 kunye noo-1990 begolide xa iisekethe ezidityanisiweyo zazalwa, zakhula kunye noshishino lwesekethe oludityanisiweyo, kubandakanya inkokeli yangoku yaseTexas Instruments (1930), owayesakuba yinkokeli yeNational Semiconductor. (1959), kunye nendawo yesibini yangoku i-Adenor (1965), ixhomekeke ekuqokeleleni kokuqala kobuchwepheshe be-analog (Yazi-indlela) ukwenza ubuchule be-Core.

Inkokeli ikude phambili kumacandelo ahlukeneyo emarike ye-analog chip

Phakathi kwe-analog ICs, ulawulo lwamandla yeyona marike inkulu ngobukhulu malunga ne-US $ 21.6 yeebhiliyoni okanye i-42%;imakethi yesixokelelwano somqondiso yi-US$14.3 yeebhiliyoni (28%) kunye neRF kunye nezinye iimveliso zentengiso malunga ne-US$15.8 yeebhiliyoni okanye i-30%.Kwicandelo le-amplifier, i-Texas Instruments ibamba phantse isithathu kwimarike (29%), kunye ne-ADENO yesibini (18%).Kwicandelo lokuguqulwa kwedatha, i-ADENO yinkokeli epheleleyo, okwangoku ibambe isiqingatha semakethe yokuguqula idatha (48%) kwaye inomkhokeli wexesha elide phezu kwabakhuphisana nabo.Kwicandelo lolawulo lwamandla, inkokeli, iTexas Instruments, ibambe ngaphezulu kwekota yemarike (21%), kunye neQualcomm (15%), iADENO (13%), iMexico (12%), kunye noInfineon (10%). izabelo ezifanayo.
