Makhalidwe a Zamalonda

Kodi atsogoleri 10 otsogola padziko lonse lapansi a analogi anakhala bwanji?

M'mbiri yonse, atsogoleri a analogi akukula kuchokera kumisika yayikulu.China, yomwe pakadali pano ili ndi msika waukulu kwambiri wa semiconductor komanso kukula kwakukulu, ikuyembekezeka kubwereza zomwe zidapangitsa kuti ADENO ikule mwachangu.

Magwero a data yonse ndi chizindikiro cha analogi, ndipo tchipisi ta analogi ndi mabwalo ophatikizika a analogi pokonza ma sign a analogi.Zizindikiro za analogi ndi zizindikiro zomwe zimapitirira nthawi ndi matalikidwe, pamene zizindikiro za digito ndi zizindikiro zomwe zimasiya nthawi ndi matalikidwe.Chizindikiro chakunja chikasinthidwa ndi sensa kukhala chizindikiro chamagetsi, ndi chizindikiro cha analogi chomwe chimakulitsidwanso ndikusefedwa mu dongosolo lomwe lili ndi chip analogi.Chizindikiro cha analogi chosinthidwa chikhoza kutulutsidwa kudongosolo la digito kuti lisinthidwe kudzera pa chosinthira cha data kapena mwachindunji kwa actuator.

Makina osakanizidwa amtundu wa digito-to-analog amaphatikizapo mafoni am'manja, makompyuta amunthu, makamera a digito, maikolofoni, ndi oyankhula, ndi zina zambiri m'gawo la ogula, zowunikira kutentha, ma electrocardiographs, makina a ndege m'gawo la mafakitale, kubweza zowonetsera m'gawo lamagalimoto, ndi zina zambiri. .Chipisi cha analogi chili paliponse.

Zizindikiro zimafalitsidwa mu mawonekedwe a magetsi ndipo zimagawidwa mu mitundu iwiri ya zizindikiro za analogi, zofooka ndi zamphamvu, malingana ndi mphamvu zamakono / magetsi.Zogulitsa za ma Signal chain ndizomwe zimakonza mphamvu zofooka.Zopangira zowongolera mphamvu zimakhala ndi udindo wokonza mphamvu zamphamvu, komanso mphamvu zofooka.

Msika wapadziko lonse wa analogi chip msika ndi pafupifupi US $ 60 biliyoni.Msika wapadziko lonse wa mabwalo ophatikizika ndi USD 340.2 biliyoni, mabwalo a analogi amawerengera 15%.Mwa mabwalo a analogi, msika wamakina osindikizira ndi US $ 14.3 biliyoni, ndipo msika wowongolera mphamvu ndi US $ 21.6 biliyoni.Kuyambira ndi op-amp yoyamba yophatikizika yomwe idawonekera mu 1968, pofika 2018, tchipisi ta analogi zidakhala bizinesi yapadziko lonse lapansi pafupifupi $60 biliyoni.

Pakalipano, makampani 10 apamwamba a analogi chip ali ndi gawo loposa theka la msika.Mu 2018, makampani 10 apamwamba kwambiri a chip analogi anali Texas Instruments (TI), Adenor (ADI), Infineon, Skyworks, ST Microelectronics, NXP, Maxim, On Semiconductor, ndi On Semiconductor.Maxim, On Semi, Microchip, ndi Renesas.

Pakati pawo, Texas Instruments imakhazikika pa kayendetsedwe ka mphamvu ndipo ndi mtsogoleri pamunda uwu;ADI idayamba ndi ma amplifiers ogwirira ntchito ndipo ndi mtsogoleri wa otembenuza ma data, omwe ali ndi gawo lalikulu pamsika mu op-amps ndi kasamalidwe ka mphamvu.Infineon adachotsedwa ku Siemens Group ndipo ndi kampani yodziyimira payokha yodziyimira payokha.Makampani omwe ali apamwamba kwambiri a analog chip, omwe adakhazikitsidwa koyambirira kwa zaka za m'ma 1960 ndi zaka za m'ma 1990 pomwe mabwalo ophatikizika adabadwa, adakulira limodzi ndi makampani ophatikizira ozungulira, kuphatikiza mtsogoleri wapano Texas Instruments (1930), mtsogoleri wakale wa National Semiconductor. (1959), ndi malo achiwiri apano Adenor (1965), kudalira kusonkhanitsa koyambirira kwaukadaulo wa analogi (Kudziwa-momwe) kuti apange luso la Core.

Mtsogoleriyo ali patsogolo kwambiri m'magawo osiyanasiyana a msika wa chip analogi

Pakati pa ma IC analogi, kasamalidwe ka mphamvu ndi msika waukulu kwambiri wokhala ndi pafupifupi US $ 21.6 biliyoni kapena 42%;msika wama signature ndi US $ 14.3 biliyoni (28%) ndipo msika wa RF ndi zinthu zina uli pafupi US $ 15.8 biliyoni kapena 30%.Mugawo la amplifier, Texas Instruments imakhala ndi gawo limodzi mwa magawo atatu a msika (29%), ndi ADENO yachiwiri (18%).Mu gawo losinthira deta, ADENO ndiye mtsogoleri wokhazikika, yemwe panopa ali ndi theka la msika wa data converter (48%) ndipo ali ndi nthawi yayitali pa mpikisano wake.Mu gawo loyang'anira mphamvu, mtsogoleri, Texas Instruments, ali ndi gawo limodzi mwa magawo anayi a msika (21%), pomwe Qualcomm (15%), ADENO (13%), Mexico (12%), ndi Infineon (10%) ali ndi magawo ofanana.
