The following graph (
Figure 63) shows an example of C
in and Cfeed influence.
4.4
Power dissipation and efficiency
Hypotheses:
●
Voltage and current in the load are sinusoidal (Vout and Iout).
●
Supply voltage is a pure DC source (VCC).
Regarding the load we have:
and
Therefore, the average current delivered by the supply voltage is:
The power delivered by the supply voltage is:
Then, the power dissipated by each amplifier is:
