PSRR and improvement of power supply noise rejection
Figure 28.
Circuit for power supply bypassing
Figure 29 shows how the power supply noise rejection evolves versus frequency depending
on how carefully the power supply decoupling is achieved.
Figure 29.
Power supply noise rejection
Criteria for choosing the ferrite:
●
In DC, the resistance (R) of the ferrite must be as low as possible to keep +5V power
supply on the chip.
●
In AC, along a 30MHz bandwidth (HD spectrum), the equivalent impedance (Z=R+jX)
must be as high as possible to optimize rejection of the noise generated by the power
supply.
