In high frequency electronic circuit, how to differentiate between coupling capacitance, and the bypass capacitor, can according to the size of the capacitance of the judge?

CodePudding user response:

To judge according to the function, not only judged according to the size of the capacitor,

CodePudding user response:

For the power supply circuit, general input filter out high frequency interference signal is the bypass capacitor, decoupling capacitor on the output side, general dc signal is often used,

CodePudding user response:

Depends on how high frequency, more than 100 m in the circuit is greater than 1000 pf capacitor mostly of decoupling capacitors (bypass capacitors), a few circuit also use on the coupling, the specific use or to the circuit diagram,

CodePudding user response:

According to the frequency characteristic of the material
