Measuring power supply ripple properly is an art in itself. Figure 1 shows an example where a neophyte engineer grabbed a scope and got it all wrong. His first mistake was using a scope probe with ...

After some torture testing to make sure it wouldn’t blow up, he used it to measure the ripple on a bench power supply. It’s a neat little circuit that ended up being a good learning experience ...

One of the biggest mistakes that a relatively inexperienced system builder will make is to place all the component focus on the most powerful processor, motherboard and graphics card while trying to ...

How many integrated circuits do you need to build up a power ... the ripple. (Hint: more is better.) And then it’s off to build. The end result is a very simple unregulated power supply ...

This ripple is not always due to the switching regulator, but sometimes is due to what the power supply is driving.

Figure 4. Worst-case PSRR performance of a 0.5μm CMOS charge-pump boosted NMOS LDO: (a) supply and (b) resulting -46 dB output ripple For additional details, questions, and/or comments, please contact ...

This white paper discusses a method for driving high-frequency sinusoidal ripple over capacitive loads for power supply rejection ratio (PSRR) testing, an important performance parameter for many ...

If the contribution of the ESR ripple surpasses the capacitive ripple, the power supply with COT will be stabilized. The downside is that the output voltage ripple will increase, which poses ...

If you're in the process of building your PC, one of the most important components to consider is which power supply unit you will ... little bit can have a huge ripple effect.
