daim iav tam sim no
Daim iav tam sim no yooj yim yog ib qho khoom siv peb-kauj ruam, thiab daim duab hauv qab no qhia nws cov schematic. N1 nyob rau hauv daim duab yog lub input node, uas yog lub input davhlau ya nyob twg uas tau txais ib tug polarity tam sim no I1; N2 yog cov khoom tso tawm, uas yog lub davhlau ya nyob twg tso zis uas tuaj yeem muab cov zis tam sim no I2, thiab I2 yog daim ntawv theej (copy) ntawm I1, uas yog, I2 thiab I2 I1 ntws hauv tib txoj kev thiab muaj nqi tib yam. Nws kuj tuaj yeem hais tias I2 ua raws li I1; N0 yog cov node, thiab tam sim no nyob rau hauv node yog cov lej ntawm I1 thiab I2.
Daim iav tam sim no yuav tsum muaj peb yam yooj yim hauv qab no.
① Tam sim no I 2 ntawm cov khoom tso tawm yuav tsum muaj kev ywj pheej ntawm qhov hluav taws xob V 2 ntawm lub node N 2, thiab V 2 raug tso cai ua rau muaj peev xwm sib txawv ntawm cov node N 0 los ntawm ntau yam puas millivolts mus rau ob peb volts, uas yog, qhov nce ntawm node N 2. Quantitative output resistance los yog AC me teeb liab tso zis tsis kam r 0 (feem ntau nws yuav tsum yog AC tso zis impedance Z o) yuav tsum siab heev, hom phiaj. tsis kawg.
② Lub DC voltage V1 ntawm lub input node N1 yuav tsum me me, feem ntau yog ntau pua millivolts txawv ntawm cov node N0, thiab qhov voltage V1 yog ib txwm ywj siab ntawm incremental hloov ntawm cov input tam sim no I1, uas yog , qhov me me-cim AC input tsis kam ri (feem ntau hu ua AC input impedance Z i) yuav tsum qis qis, qhov zoo tshaj xoom.
③ Kev hloov pauv tam sim no M=I 2/I 1 yuav tsum nyob ze li 1 li sai tau, thiab tsis muaj dab tsi cuam tshuam nrog lub amplitude ntawm tam sim no nyob rau hauv ntau yam ntawm ntau tenfold hloov, uas yog, zoo tagnrho tam sim no daim iav yog ib qho linear element. Nyob rau hauv daim ntawv thov ntawm lub teeb liab kis tau tus mob txoj kev, lub amplitude-zaus teb thiab theem-zaus teb ntawm qhov zoo tagnrho daim iav tam sim no hloov pauv piv M yuav tsum yog ywj siab ntawm zaus ntawm lub teeb liab.
