Kev siv fais fab IC hauv xov tooj ntawm tes

Cov xov tooj ntawm tes yog cov ntawv thov tseem ceeb tshaj plaws rau kev tswj fais fab ICs. Multimedia thiab 3G lub xov tooj ntawm tes txuas ntxiv mus ntxiv qhov kev thov rau cov yeeb yaj kiab siab, cov ntaub ntawv multimedia streaming, audio playback, pom meej dua thiab kev lom zem ntau dua, tab sis cov yam ntxwv no siv ntau lub zog, feem ntau tsis zoo ib yam. Raws li qhov kev xav tau tam sim no nce ntxiv, lawv xav tau ntau lub zog, xws li hloov kho dua tshiab los ntawm 2G lub suab xov tooj mus rau 3G video xov tooj, kev xav tau hluav taws xob ob npaug. Nyob rau hauv tib lub xov tooj ntawm tes los sib sau ua ke ntau ntau lub zog, nws lub zog siv kuj tseem yuav nce ntxiv, uas yog qhov pom tseeb hauv kev txhim kho yav tom ntej ntawm kev tswj fais fab chips.

LDOs siv LDOs los txhawb txhua qhov chaw ntawm lub xov tooj ntawm tes. LDOs muaj cov kev hloov pauv tsis zoo, cov pob me me, cov khoom siv qis qis thiab cov suab nrov tsawg. Txawm li cas los xij, lawv muaj kev hloov pauv tsis zoo thiab tsuas yog siv tau rau hauv daim ntawv thov nyiaj, ntxiv rau LDO. Efficiency nyob ntawm qhov piv ntawm cov zis rau input voltage. Thaum lub input voltage yog 3.6V thiab cov zis voltage yog 1.5V, qhov efficiency tsuas yog 41.7%. Qhov kev ua haujlwm qis no yuav tsis tsuas yog nkim ntau lub zog thaum cov zis tam sim no loj, tab sis kuj ua rau nti hluav taws xob cuam tshuam rau qhov system stability. Lub Cheebtsam ntawm 3G xov tooj ntawm tes yuav tsum muaj ntau theem voltage ntawm lub hwj chim mov. Feem ntau, tshwj xeeb tshaj yog thaum qhov sib txawv voltage loj, LDO tau nyuaj ua kom tau raws li qhov yuav tsum tau muaj lub zog, yog li cov tshuaj DC / DC dhau los ua kev daws teeb meem los hloov LDO.

Qhov zoo ntawm DC / DC hloov dua siab tshiab yog ob qho tib si siab thiab qis, thiab kev ua haujlwm siab. Tam sim no, muaj tsis siv neeg PFM / PWM hom thiab DC / DC + LDO dual hom kev tswj fais fab kev daws teeb meem, txawm hais tias tus nqi ntawm cov kev daws teeb meem yuav siab. Hauv LDO, nws tuaj yeem daws qhov teeb meem ntawm LDO inefficiency thiab tsuas yog siv tau rau kev txo qhov hluav taws xob. Qhov nce ntawm 3G xov tooj ntawm tes ntau lawm thiab kev txhim kho ntawm lub xov tooj ntawm tes fais fab tswj kev ua haujlwm yuav txhawb nqa txoj kev loj hlob ntawm lub xov tooj ntawm tes fais fab IC kev lag luam rau qee qhov.

Fais fab mov ic siab tam sim no / qis tso zis voltage daim ntawv thov

Txij li lub moos ntawm cov nti digital tau nrawm dua thiab nrawm dua, nws txhais tau hais tias cov tsav tam sim no tau loj dua thiab loj dua. Yav dhau los, tsuas yog cov linear voltage regulator xav tau. Tam sim no, hloov regulator yog xav tau. Yav dhau los, tsuas yog ib theem hluav taws xob xav tau. Tam sim no, xav tau ob lossis ntau lub zog siv hluav taws xob. . Tsis tas li ntawd, vim hais tias CPU tau nrawm dua thiab nrawm dua, cov cua kub dissipation tau dhau los ua lub hauv paus rau nws txoj kev loj hlob. Yog li ntawd, nrog ntau cov tub ntxhais thev naus laus zis, Intel twb tau npaj 80 core CPUs, uas yuav tsum tau muaj zog ntau dua.
