Equation e latelang e etsa mocheso oa transistor mabapi le base-emitter voltage (VBE).

Equation 1. Kamano Pakeng Tsa Mocheso oa Transistor ho Base-Emitter Voltage (VBE)Moo:
- T—Mocheso ho Kelvin
- q - tefiso ea elektrone (1.60 × 10−19 C)
- VBE-base-emitter voltage
- k—Boltzmann kamehla (1.38 × 10−23 J∙K−1)
- IC - mokelli oa hona joale
- KE—mokhoa oa ho tlala metsi ka morao

Ideality Factor (η-Factor) Mismatch

Ha o etsa tekanyo ea mocheso oa matekoane ka ho sebelisa mocheso o ka ntle oa mocheso, ho nepahala ha tekanyo ea mocheso ho itšetlehile ka litšobotsi tsa diode e ka ntle. The ideality factor ke parameter ea diode e hole e lekanyang ho kheloha ha diode ho tloha boitšoarong ba eona bo nepahetseng.
Hangata u ka fumana ntlha e nepahetseng ho leqephe la data ho tsoa ho moetsi oa diode. Li-diode tse fapaneng tsa mocheso oa kantle li u fa boleng bo fapaneng ka lebaka la boqapi bo fapaneng le mahlale a tšebetso ao ba a sebelisang.
Ho se lumellane ho ka baka phoso e kholo ea tekanyo ea mocheso. Ho qoba phoso e kholo, Intel e khothaletsa hore u khethe chip e utloang mocheso e nang le ntho e ka lokisoang. O ka fetola boleng ba factority factor ho chip ho tlosa phoso e sa lumellaneng.

Example 1. Ideality Factor Contribution to the Temperature Measurement Error

Example bontša kamoo ideality factor e tlatsetsang phoso ea tekanyo ea mocheso. Ka mohlalaample, lipalo li bonts'a ho se lumellane ho nepahetseng ho bakang phoso e kholo ea tekanyo ea mocheso.

Equation 4. Ideality Factor Kamano le Mocheso o Lekanyelitsoeng

Moo:

ηTSC - ntlha ea bohlokoa ea chip e utloang mocheso
TTSC - mocheso o baloang ke chip e utloang mocheso
ηRTD - ntlha ea bohlokoa ea diode e hole ea mocheso
TRTD - mocheso ho diode e hole ea mocheso

Mehato e latelang e hakanya tekanyo ea mocheso (TTSC) ka chip e utloang mocheso, e fuoa litekanyetso tse latelang:

Ideality factor of the temperature sensor (ηTSC) ke 1.005
Ideality factor of the remote temperature diode (ηRTD) ke 1.03
Thempereichara ea 'nete sebakeng sa "remote temperature diode" (TRTD) ke 80°C

Fetola TRTD ea 80°C ho Kelvin: 80 + 273.15 = 353.15 K.
Sebelisa Equation 4. Mocheso o baloang ke chip e utloang mocheso ke 1.005 × 353.15 = 344.57 K.TTSC = 1.03

Fetolela boleng bo baliloeng ho Celsius: TTSC = 344.57 K - 273.15 K = 71.43°C Phoso ea mocheso (TE) e bakiloeng ke ho se lumellane ho nepahetseng:
TE = 71.43°C – 80.0°C = –8.57°C

Letoto la Phoso ea Resistance

Ho hanyetsa letoto la lithapo tsa P le N ho tlatsetsa phosong ea tekanyo ea mocheso.

Letoto la ho hanyetsa e ka ba ho tloha:

Ho hanyetsa ka hare ho pini ea P le N ea diode ea mocheso.
The board trace resistance, for example, mohlala o molelele oa boto.

Ho hanyetsa letoto ho baka molumo o eketsehilengtage ho theoha tseleng ea ho lemoha mocheso 'me ho fella ka phoso ea tekanyo, e amang ho nepahala ha tekanyo ea mocheso. Ka tloaelo, boemo bona bo etsahala ha u etsa tekanyo ea mocheso ka chip e utloang mocheso oa 2-joale.

Setšoantšo sa 3. Ka hare le ka On-Boto Series ResistanceHo hlalosa phoso ea mocheso e etsahetseng ha letoto la ho hanyetsa le eketseha, moetsi o mong oa mocheso oa mocheso o fana ka boitsebiso bakeng sa phoso ea mocheso oa diode e hōle khahlanong le khanyetso.
Leha ho le joalo, o ka felisa phoso ea ho hanyetsa letoto. Setsi se seng se lemohang mocheso se na le karolo e hahelletsoeng ka har'a letoto la ho thibela ho hanyetsa. Karolo ea ho hlakola letoto la ho hanyetsa e ka felisa khanyetso ea letoto ho tloha ho makholo a 'maloa a Ω ho isa ho mefuta e fetang likete tse' maloa tsa Ω.
Intel e khothaletsa hore u nahane ka karolo ea ho hlakola letoto la ho hanyetsa ha u khetha chip e utloang mocheso. The tšobotsi ka tsela e iketsang felisa mocheso phoso bakoang ke ho hanyetsa ea routing ho transistor remoutu.

Hlokomela: Intel e khothalletsa hore u sebelise chip e utloang mocheso e nang le matšeliso a hahelletsoeng ka hare. Haeba chip e utloang mocheso e sa tšehetse tšobotsi ena, o ka sebelisa matšeliso nakong ea ts'ebetso ea poso ka mokhoa o hlophisitsoeng kapa software.
Matšeliso a Offset a fetola boleng ba rejisete ea offset ho tsoa ho chip e utloang mocheso ho felisa phoso e baliloeng. Ho sebelisa tšobotsi ena, o tlameha ho etsa tlhahlobo ea mochesofile ithuta le ho khetholla boleng ba offset ho etsa kopo.

U tlameha ho bokella litekanyo tsa mocheso ho pholletsa le sebaka sa mocheso se lakatsehang ka li-setting tsa kamehla tsa chip e utloang mocheso. Kamora moo, etsa tlhahlobo ea data joalo ka mohlala o latelangample ho fumana boleng ba offset ho sebetsa. Intel e khothaletsa hore u leke li-chips tse 'maloa tse utloang mocheso ka diode tse' maloa tse hole ho netefatsa hore u koahela phapang ea karolo ho ea ho karolo. Ebe, sebelisa karolelano ea litekanyo tlhahlobisong ho fumana litlhophiso tseo u ka li sebelisang.
U ka khetha lintlha tsa mocheso ho latela maemo a ts'ebetso ea sistimi ea hau.
