Cov txheej txheem siv bandgap yog ib txoj hauv kev siv ntau tshaj plaws los tsim kom muaj qhov kub thiab txias-yooj yim siv hluav taws xob. Bob Widlar, tus kws tshaj lij hluav taws xob zoo nkauj, tau tsim lub hauv paus rau hnub no lub bandgap voltage references nyob rau hauv lig 1960s.

PTAT voltage yog dab tsi?

V BE qhov hluav taws xob ntawm qhov yooj yim diode txuas nrog transistor ntawm daim duab 14.1(a) tuaj yeem siv los ua kom muaj kev tswj hwm tam sim no ib yam, raws li qhia hauv daim duab 14.3. … Peb xa mus rau qhov no yog PTAT lossis Proportional To Absolute Temperature current.

V yog dab tsi?

Ib qhov siv hluav taws xob, lossis V ref, yog ib lub cuab yeej precision tsim los tswj qhov tseeb, tsis tshua muaj suab nrov tsis tu ncua cov zis voltage. Qhov zoo tshaj plaws, cov zis yuav tsum nyob tas li txawm tias tsis muaj xws li qhov kub thiab txias, qhov hluav taws xob, lossis qhov hloov pauv tam sim no. V refs muaj nyob rau hauv kev sib txawv topologies.

Iptat yog dab tsi?

Definition. PTAT. Cov neeg tham txog qhov no (Facebook) PTAT. Proportional to Absolute Temperature (electronic circuit transistor biasing)

Vim li cas siv hluav taws xob tau txais?

Ib qhov siv hluav taws xob yog ib qho khoom siv hluav taws xob lossis hluav taws xob uasua qhov tsis tu ncua DC (ncaj-tam sim no) tso zis hluav taws xobtsis hais txog qhov hloov pauv ntawm lwm yam xwm txheej xws li kub, barometric siab, av noo., kev thov tam sim no, lossis kev hla ntawmlub sij hawm.

Vim li cas thiaj li ua pov thawj qhov kev soj ntsuam?

Kev Tshawb Fawb Txog Kev Pom Zoo (CFA) yog cov txheej txheem txheeb cais siv los txheeb xyuas cov qauv ntawm cov txheej txheem pom zoo. CFA tso cai rau tus kws tshawb fawb los ntsuas qhov kev xav tias muaj kev sib raug zoo ntawm cov kev hloov pauv tau pom thiab lawv cov hauv paus latent tsim muaj.

Qhov twg yog genicular anastomosis?

a periarticular arterial network hla pem hauv ntej thiab ob sab ntawm lub hauv caug, tsim los ntawm cov ceg ntawm cov hlab ntsha genicular, ntawm tsib cov hlab ntsha genicular los ntawm popliteal, ntawm tibial anterior rov tshwm sim, thiab ntawm fibular circumflex ceg ntawm lub posterior tibial.
