Qhov laj thawj tag nrho rau cascading amplifiers yog qhov kev xav tau nce ntxiv hauv cov khoom siv hluav taws xob kom tau raws li qhov yuav tsum tau ua, piv txwv li, txhawm rau ua kom lub teeb liab muaj zog hauv TV lossis xov tooj cua receiver. Siv lub cascade, lossis multistage, amplifier tuaj yeem muab koj tus qauv tsim nrog qhov nce siab dua tam sim no lossis qhov nce voltage.
Qhov zoo ntawm cascade amplifier yog dab tsi?
Qhov zoo ntawm cascade amplifier yog:
- Txhim kho kev ua haujlwm thiab kev ua haujlwm zoo.
- siab tshaj plaws flatness ntau ntau.
- Cov suab nrov tsawg tsawg hauv thaj tsam ntawm 1-10GHz.
- nce nce.
- Ntau bandwidth tso cai rau cov cuab yeej siv dav dav rau cov khoom siv hluav taws xob siab.
- Hight input thiab output impedances.
Cascaded op-amp yog dab tsi?
Thaum op amp circuits yog cascaded, txhua lub voj voog hauv txoj hlua hu ua theem; lub thawj cov tswv yim teeb liab tau nce los ntawm qhov nce ntawm tus kheej theem. Op amp circuits muaj qhov zoo dua uas lawv tuaj yeem raug cascaded yam tsis hloov lawv cov tswv yim - tawm kev sib raug zoo.
Yuav ua li cas thaum amplifiers raug kaw?
A cascaded amplifier tsuas txhais tau tias ntau lub amplifiers lumped ua ke rau hauv ib lub cuab yeej. Cov zis ntawm ib theem amplifier txuas nrog rau theem input amplifier. … Muab cov theem amplifier tso rau hauv cov yeeb yaj kiab hauv txoj kev no tso cai rau kev nce ntxiv rau kev siv lub teeb liab tawm tswv yim.
Vim li cas op-amp saturate?
Nyobop-amp yuav saturate yog tias qhov input voltage nce ntau dhaulossis yog tias qhov nce ntau dhau.
