Amplifier vs Operational Amplifier
Amplifiers yog cov khoom siv hluav taws xob tseem ceeb heev siv hauv hluav taws xob thiab ntau yam haujlwm. Amplifier yog ib qho cuab yeej uas yuav ua rau kom lub zog ntawm lub teeb liab muab tswv yim siv lub zog sab nraud. Amplifiers yog dav siv nyob rau hauv kev lag luam xws li electronics, cov ntaub ntawv tau, suab engineering, hluav taws xob engineering, teeb liab ua, thiab ntau yam hauj lwm. Hauv tsab xov xwm no, peb yuav tham txog dab tsi amplifiers thiab kev ua haujlwm amplifiers yog, kev ua haujlwm ntawm amplifiers thiab kev ua haujlwm amplifiers thiab lawv daim ntawv thov, thiab thaum kawg kev sib piv ntawm amplifier thiab kev ua haujlwm amplifier, qhia txog qhov txawv ntawm lub amplifier thiab kev ua haujlwm amplifier thaum kawg..
Amplifier yog dab tsi?
Amplifiers yog cov khoom siv uas siv los ua kom lub zog ntawm cov teeb liab tawm tswv yim nrog kev pab ntawm lub zog sab nraud. Cov teeb liab feem ntau yog nyob rau hauv daim ntawv ntawm cov teeb liab tam sim no lossis cov teeb liab voltage. Lawv tuaj yeem muaj daim ntawv xws li airflow lossis dej ntws. Amplifiers muaj ntau yam zoo uas yuav tsum tau xav txog. Qee qhov tseem ceeb tshaj plaws ntawm cov khoom no yog nce, bandwidth, efficiency, linearity suab nrov thiab tso zis ntau yam.
Gain ntawm lub amplifier txhais tau tias yog qhov piv ntawm qhov amplitude ntawm lub teeb liab tso zis rau lub amplitude ntawm lub teeb liab input. Bandwidth ntawm lub amplifier yog qhov ntau zaus uas qhov nce ntawm qhov siab tshaj plaws. Amplifiers kuj raug cais raws li qhov ua tau zoo. A chav kawm A amplifier muaj kev ua haujlwm tsawg heev thaum chav kawm D amplifiers muaj kev ua haujlwm siab heev. Amplifiers yog ib qho tseem ceeb heev hauv kev lag luam xws li suab paj nruag thiab suab engineering, kev teeb tsa, kev tshuaj xyuas cov ntaub ntawv thiab ntau yam haujlwm.
Lub Amplifier Ua Haujlwm yog dab tsi?
Kev ua haujlwm amplifiers, uas feem ntau hu ua op-amps, yog hom amplifiers uas muaj txiaj ntsig zoo hauv kev lag luam hluav taws xob. 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 qhov sib txawv amplifier, uas txhais tau hais tias lub amplifier amplifies qhov voltage sib txawv ntawm inverting input thiab cov inverting input. Qhov no tso cai rau op-amp ua haujlwm ntawm hom teeb liab tsis lees paub. 741 op-amp yog ib qho ntawm feem ntau thiab muaj kev vam meej op-amps hauv keeb kwm ntawm kev tsim khoom. Kev ua haujlwm amplifiers muaj txiaj ntsig zoo hauv kev sib piv cov teeb liab, txo suab nrov, hloov pauv, ntsuas, sib txawv, kev sib koom ua ke, sib ntxiv, thiab rho tawm circuits.
Qhov txawv ntawm Amplifier thiab Kev Ua Haujlwm Amplifier yog dab tsi?
• Amplifiers tuaj yeem yog hluav taws xob lossis khoom siv hauv cov ntsiab lus sib xws thaum lub tshuab ua haujlwm yog cov khoom siv hluav taws xob.
• Amplifiers, feem ntau, muaj qhov txwv tsis pub muaj peev xwm nthuav tawm DC cov cim tab sis txhua tus op-amps muaj peev xwm ua kom nrov DC cov cim.
