Voltage-zaus converter
Ib tug voltage-rau-frequency converter (VFC) yog ib qho khoom siv hluav taws xob uas hloov cov teeb liab input voltage rau hauv lub teeb liab zaus. VFCs tau siv dav hauv ntau lub tshuab hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas cov teeb liab analog yuav tsum tau hloov mus rau cov teeb liab digital. Lawv feem ntau siv nyob rau hauv sensor interfaces, cov ntaub ntawv nrhiav tau, systems kev sib txuas lus, thiab tsis siv neeg tswj systems.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm VFC yog los hloov cov teeb liab input voltage rau hauv cov zis zaus teeb liab proportional rau nws. Internal circuit feem ntau muaj xws li ib tug sib piv, ib tug integrator, thiab ib tug oscillator. Lub input voltage yog hloov mus rau hauv lub mem tes teeb liab los ntawm kev sib piv, lub integrator integrates lub mem tes teeb liab, thiab oscillator generates ib zaus teeb liab raws li lub integrated voltage teeb liab. Yog li, kev hloov pauv hauv qhov hluav taws xob input ncaj qha cuam tshuam rau qhov tso zis zaus, ua tiav qhov hloov hluav taws xob mus rau zaus.
Cov yam ntxwv tseem ceeb ntawm VFC
High linearity
VFCs tuaj yeem hloov cov teeb liab hluav taws xob mus rau hauv cov cim zaus nrog cov kab sib chaws siab, ua rau lawv muaj txiaj ntsig zoo hauv kev ntsuas ntsuas thiab tswj cov ntawv thov.
Dav Dynamic Range
VFCs tuaj yeem tswj tau ntau yam ntawm cov khoom siv hluav taws xob hluav taws xob thiab tsim cov cim zaus sib xws, ua rau lawv haum rau ntau yam kev siv.
Kev siv hluav taws xob tsawg
VFCs feem ntau muaj kev siv hluav taws xob tsawg, ua rau lawv haum rau cov khoom siv roj teeb uas siv tau thiab lwm yam kev siv hluav taws xob tsawg.
Muaj peev xwm tiv thaiv kev cuam tshuam
Txij li thaum lub teeb liab tso zis yog ib lub teeb liab zaus, VFCs muaj zog tiv thaiv electromagnetic cuam tshuam, tso cai rau lawv ua hauj lwm ruaj khov nyob rau hauv complex electromagnetic ib puag ncig.
