Inverting vs Non Inverting Amplifier
Inverting amplifier thiab non-inverting amplifier yog ob lub amplifiers uas yog tsim los siv lub lag luam amplifier. Inverting amplifier siv lub inverting input ntawm lub lag luam amplifier raws li lub ntsiab input thaum lub inverting input tsis yog grounded. Cov tsis-inverting amplifier siv cov inverting input ntawm lub lag luam amplifier ua lub ntsiab input thaum lub inverting input yog grounded. Ob hom amplifier no tseem ceeb heev hauv kev ua haujlwm amplifier circuits. Cov circuits no tau siv dav hauv kev ntxiv circuits, multipliers, sib txawv circuits, integrating circuits, logic gates, thiab ntau lwm yam circuits tsim los ntawm kev ua haujlwm amplifier. Hauv kab lus no, peb yuav tham txog dab tsi inverting amplifier thiab non-inverting amplifier yog, lawv daim ntawv thov, qhov zoo sib xws ntawm ob qho no, thiab thaum kawg qhov txawv ntawm inverting amplifier thiab non-inverting amplifier.
Dab tsi yog Inverting Amplifier?
Yuav kom nkag siab txog dab tsi inverting amplifier yog ib qho yuav tsum xub nkag siab tias qhov ua haujlwm amplifier yog dab tsi. Ib qho op-amp muaj ob lub input terminals, ob lub hwj chim inputs thiab ib lub qhov tso zis tawm. Cov input terminals yog hu ua inverting input thiab non-inverting input. Qhov zoo tshaj plaws op-amp muaj qhov nce ntawm infinity nrog infinite kuj ntawm input terminals thiab xoom tsis kam nyob rau hauv cov zis davhlau ya nyob twg. Nyob rau hauv kev xyaum, lub input kuj yog heev loj, thiab cov zis kuj yog heev me me. Qhov siab tshaj plaws tso zis hluav taws xob ntawm op-amp yog sib npaug rau kev khiav hauj lwm voltage los ntawm lub hwj chim sab nraud. Op-amp yog ib qho txawv amplifier, uas txhais tau hais tias lub amplifier amplifies qhov voltage sib txawv ntawm inverting input thiab cov inverting input.
Lub inverting amplifier yog tsim los ntawm kev muab cov tswv yim rau lub inverting input thiab grounding qhov tsis-inverting kawg. Lub teeb liab tso zis yog saturated txawm rau ib tug me me input teeb liab vim lub theoretical infinite nce ntawm op-amp. Lub teeb liab tso zis yog 1800 tawm ntawm theem (inverted) nrog lub teeb liab input. Ib qho kev tawm tswv yim resistor thiab ib qho input resistor txuas nrog rau cov circuits thiaj li yuav txo tau qhov nce thiab stabilize lub teeb liab. Lub inverting amplifier muaj qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov input resistor thaum lub tswv yim resistor yog tsau.
Dab tsi yog qhov Tsis-inverting Amplifier?
Tsis yog inverting amplifier yog lwm hom amplifier tsim los ntawm kev ua haujlwm amplifier. Lub teeb liab tso zis, thaum ib qho kev tawm tswv yim muab rau qhov tsis yog inverting input, yog nyob rau theem nrog cov teeb liab input. Thaum ib qho kev tawm tswv yim resistor nrog cov lus tawm tswv yim tsis zoo raug muab thiab muab tso rau hauv qhov kev tawm tsam, lub amplifier tau ruaj khov. Nyob rau hauv hom no, lub amplifier muaj ib tug linear kev sib raug zoo ntawm qhov nce thiab inverse input resistor, thaum lub tswv yim resistor yog tsau. Txawm li cas los xij, muaj tus nqi nce thaum lub tswv yim resistor yog xoom. Qhov no ua rau lub amplifier tsis inverting tsis muaj txiaj ntsig hauv kev ntxiv, sib npaug, thiab rho tawm circuits.
Qhov txawv ntawm Inverting Amplifier thiab Tsis-inverting Amplifier yog dab tsi?
• Inverting amplifier muab inverted output whereas lub non-inverting amplifier muab cov zis uas yog nyob rau hauv theem nrog input teeb liab.
• Qhov nce ntawm lub inverting amplifier, thaum siv nrog cov lus pom tsis zoo, yog ncaj qha proportional rau qhov piv ntawm cov lus tawm tswv yim resistor / input resistor. Qhov nce ntawm qhov tsis-inverting amplifier kuj yog proportional rau qhov piv txwv saum toj no tab sis nrog tus nqi cuam tshuam.
