Then
C FEED = -2---π------R-----F---1E----E---D----F----C----H- = 265pF
Application n°2 : 20Hz to 20kHz bandwidth and
20dB gain BTL power amplifier.
Components :
So, we could use for Cfeed a 220pF capacitor
value that gives 24kHz.
Designator
R1
Part Type
110k / 0.125W
Now, we can calculate the value of Cb with the R4
formula τb = 50kΩxCb >> τin = (Rin+Rfeed)xCin
R6
which permits to reduce the pop and click effects.
Then Cb >> 0.8µF.
R7
We can choose for Cb a normalized value of 2.2µF
C5
that gives good results in THD+N and PSRR.
