Lub ntiaj teb sab saum toj 10 analog chip thawj coj los ua li cas?

Thoob plaws hauv keeb kwm, analog chip thawj coj tau loj hlob los ntawm kev lag luam loj.Tuam Tshoj, uas tam sim no muaj lub lag luam loj tshaj plaws semiconductor thiab kev loj hlob siab tshaj plaws, xav tias yuav rov ua dua cov xwm txheej uas ua rau ADENO txoj kev loj hlob sai.

Lub hauv paus ntawm tag nrho cov ntaub ntawv yog lub teeb liab analog, thiab analog chips yog kev sib xyaw analog circuits rau kev ua cov cim analog.Analog signals yog cov teeb liab uas txuas ntxiv mus rau lub sijhawm thiab amplitude, thaum cov teeb liab digital yog cov teeb liab uas tsis tu ncua hauv lub sijhawm thiab amplitude.Tom qab lub teeb liab sab nraud tau raug hloov los ntawm lub sensor rau hauv lub teeb liab hluav taws xob, nws yog ib qho analog teeb liab uas yog txuas ntxiv thiab lim hauv lub kaw lus uas muaj cov analog nti.Cov txheej txheem analog teeb liab tuaj yeem tso tawm rau lub kaw lus digital rau kev ua haujlwm ntawm cov ntaub ntawv hloov pauv lossis ncaj qha mus rau tus actuator.

Cov kab ke digital-rau-analog hybrid suav nrog cov xov tooj ntawm tes, khoos phis tawj tus kheej, lub koob yees duab digital, microphones, thiab hais lus, thiab lwm yam hauv cov neeg siv khoom, ntsuas kub, electrocardiographs, aircraft systems nyob rau hauv kev lag luam sector, thim rov qab qhia nyob rau hauv automotive sector, thiab lwm yam. Analog chips yog ubiquitous.

Cov teeb liab raug xa mus rau hauv daim ntawv ntawm hluav taws xob thiab muab faib ua ob hom analog teeb liab, tsis muaj zog thiab muaj zog, nyob ntawm lub zog ntawm qhov tam sim no / voltage.Cov khoom siv hluav taws xob saw hluav taws xob yog lub luag haujlwm rau kev ua haujlwm tsis muaj zog.Lub zog tswj cov khoom lag luam feem ntau yog lub luag haujlwm rau kev ua haujlwm ntawm lub zog muaj zog, tab sis kuj muaj lub zog tsis muaj zog.

Lub ntiaj teb no analog chip lag luam chaw yog ze li ntawm US $ 60 billion.Kev ua lag luam thoob ntiaj teb rau kev sib koom ua ke yog USD 340.2 billion, nrog analog circuits suav txog 15%.Ntawm cov analog circuits, lub teeb liab saw kev lag luam yog US $ 14.3 billion, thiab lub hwj chim tswj kev lag luam yog US $ 21.6 billion.Pib nrog thawj qhov kev sib koom ua ke op-amp uas tau tshwm sim hauv 1968, los ntawm 2018, analog chips tau dhau los ua kev lag luam thoob ntiaj teb ntawm ze li $ 60 billion.

Tam sim no, saum 10 analog chip tuam txhab uas muag tuav ntau tshaj li ib nrab ntawm kev ua lag luam.Hauv 2018, 10 lub tuam txhab analog chip saum toj kawg nkaus yog Texas Instruments (TI), Adenor (ADI), Infineon, Skyworks, ST Microelectronics, NXP, Maxim, Ntawm Semiconductor, thiab Ntawm Semiconductor.Maxim, On Semi, Microchip, thiab Renesas.

Ntawm lawv, Texas Instruments tshwj xeeb hauv kev tswj fais fab thiab yog tus thawj coj hauv daim teb no;ADI pib nrog kev ua haujlwm amplifiers thiab yog tus thawj coj hauv cov ntaub ntawv hloov pauv, nrog rau kev lag luam siab hauv op-amps thiab kev tswj fais fab.Infineon tau spun tawm los ntawm Siemens Group thiab yog ib tug ntawm nws tus kheej sau npe semiconductor tuam txhab.Tam sim no cov tuam txhab ua lag luam zoo tshaj plaws analog chip, uas tau tsim nyob rau thaum ntxov 1960s thiab golden 1990s thaum integrated circuits tau yug los, loj hlob ua ke nrog kev lag luam kev sib koom ua ke, suav nrog cov thawj coj tam sim no Texas Instruments (1930), tus thawj coj National Semiconductor. (1959), thiab qhov chaw thib ob tam sim no Adenor (1965), tso siab rau qhov qub tsub zuj zuj ntawm analog thev naus laus zis (Know-how) los tsim cov peev txheej Core.

Tus thawj coj nyob deb ua ntej hauv ntau ntu ntawm kev ua lag luam analog chip

Ntawm cov analog ICs, kev tswj fais fab yog lub lag luam loj tshaj plaws nrog qhov loj ntawm $ 21.6 billion lossis 42%;lub teeb liab saw kev lag luam yog US $ 14.3 billion (28%) thiab RF thiab lwm yam khoom lag luam yog kwv yees li US $ 15.8 billion lossis 30%.Hauv ntu ntu amplifier, Texas Instruments tuav yuav luag ib feem peb ntawm kev ua lag luam (29%), nrog ADENO thib ob (18%).Hauv ntu kev hloov pauv cov ntaub ntawv, ADENO yog tus thawj coj tiag tiag, tam sim no tuav ib nrab ntawm cov ntaub ntawv hloov pauv kev lag luam (48%) thiab muaj kev coj mus ntev rau nws cov neeg sib tw.Hauv ntu kev tswj fais fab, tus thawj coj, Texas Instruments, tuav ntau tshaj ib lub hlis twg ntawm kev ua lag luam (21%), nrog Qualcomm (15%), ADENO (13%), Mexico (12%), thiab Infineon (10%) muaj zoo sib xws.
