It is a common belief that multi-layer ceramic capacitors (MLCCs) or DC power supply circuits cause audible noise, but that’s not true. The noise is generated by the PCB, not by the components. The ...

This approach enables a lower peak-power design requirement for the power supply and avoids the need for a large capacitor bank. But the output current regulation circuitry does require a separate ...

Power supply design optimises capacitors. ... Unfortunately, this approach degrades the overall power supply efficiency because it requires a secondary linear regulator. This drives the need for a ...

To improve ripple and noise specifications, DC programmable power supplies have output filters that use large capacitors that store a lot of energy. It is mainly the charge and discharge time of this ...

You can see a close-in view of the power pin artifacts FFT for the signals on the dc supply pin in Fig. 6 out to 500 MHz. The harmonics are uniformly spaced at the data rate of 20 MHz. A spurious ...
