Muaj ntau qhov kev xav tseem ceeb uas yuav tsum nco ntsoov thaum tsim lub tshuab ua haujlwm multistage.Nov yog qee yam tseem ceeb uas yuav tsum xav txog:
Thov ib daim Quote Tam sim no rau PCB Manufacturing thiab Assembly
Tau txais thiab Bandwidth Requirements
Thawj kauj ruam hauv kev tsim lub tshuab hluav taws xob multistage yog los txiav txim siab qhov yuav tsum tau nce thiab bandwidth.Qhov no yog nyob ntawm daim ntawv thov thiab qhov yuav tsum tau ua haujlwm specifications.Qhov nce ntawm txhua theem yuav tsum raug xaiv kom ua tau raws li qhov yuav tsum tau nce tag nrho, thaum lub bandwidth yuav tsum raug xaiv kom tau raws li qhov yuav tsum tau ua.
Input thiab Output Impedance
Lub tswv yim thiab cov zis impedance ntawm txhua theem yuav tsum tau ua tib zoo xaiv los xyuas kom meej qhov zoo sib xws rau cov theem ua ntej thiab nram qab no.Qhov no yog ib qho tseem ceeb kom txo cov teeb liab kev xav thiab ua kom lub zog hloov pauv mus rau theem siab tshaj plaws.
Tsis zoo Voltage
Txoj kev tsis ncaj ncees ntawm txhua theem yog qhov tseem ceeb kom ntseeg tau tias kev ua haujlwm ruaj khov thiab tawm mus.Cov txheej txheem biasing xaiv yuav tsum muab qhov yuav tsum tau quiescent tam sim no thiab voltage theem thaum txo hwj chim dissipation thiab thermal cuam tshuam.
Suab nrov thiab Distortion
Multistage amplifiers qhia ntxiv suab nrov thiab distortion piv rau ib-theem amplifiers.Kev saib xyuas yuav tsum tau ua kom txo qis cov teebmeem no los ntawm kev xaiv cov khoom tsim nyog, kev teeb tsa thiab kev tiv thaiv.
Kev ruaj ntseg
Multistage amplifiers yog nquag oscillations, tshwj xeeb tshaj yog nyob rau hauv high zaus.Kev them nyiaj tsim nyog thiab kev tawm tswv yim yuav tsum tau siv los xyuas kom meej tias kev ua haujlwm ruaj khov tshaj qhov xav tau ntau zaus.
Nyob rau hauv cov ntsiab lus, tsim ib tug multistage amplifier yuav tsum tau ua tib zoo xav txog ntau yam, nrog rau kev nce thiab bandwidth yuav tsum tau, input thiab output impedance, bias, suab nrov thiab distortion, thiab stability.Los ntawm kev ua tib zoo xav txog cov xwm txheej no, lub tshuab hluav taws xob multistage tsim tau zoo tuaj yeem muab kev ua haujlwm siab thiab kev ntseeg siab rau ntau yam kev siv.
