1. Field-cov nyhuv transistors (FETs) tuaj yeem siv rau kev nthuav dav. Vim lub siab input impedance ntawm FET amplifiers, lub coupling capacitor yuav me me, tshem tawm qhov xav tau ntawm electrolytic capacitor.
2. Lub siab input impedance ntawm FETs ua rau lawv zoo tagnrho rau impedance transformation. Lawv feem ntau yog siv nyob rau hauv lub tswv yim theem ntawm multi-theem amplifiers rau impedance transformation.
3. FETs tuaj yeem siv los ua cov resistors sib txawv.
4. FETs tuaj yeem siv tau yooj yim los ua qhov chaw tam sim no.
5. FETs tuaj yeem siv ua hluav taws xob hloov hluav taws xob.
