Noise management, induced by digital circuits on a p. c. board assembly, deserves the attention of power supply designers and those mastering digital, analog, and mixed-mode application problems ...

One of the longest running problems in PCB (printed-circuit-board) design has been trying to figure how much decoupling capacitors you need for your design. PCB engineers often use too much decoupling ...

The first thing you may want to do is check if the default control loop (i.e. the PID settings that the product is delivered with) is good enough in terms of stability and load transient performance.

Deep-submicron systems-on-a-chip (SoCs) require a power-grid voltage drop of much less than 10% of VDD. Decoupling capacitors, or decaps, help achieve this goal by minimizing switching noise.

Everyone knows that the perfect capacitor to decouple the power rails around ICs is a 100 nF ceramic capacitor or equivalent, yet where does this ‘fact’ come from and is it even correct? These are the ...

Most ICs need to be decoupled from their power supply, usually with a 0.1uF capacitor between each power pin and ground. Decoupling is usually used to remove noise and to smooth power fluctuations.

The CC-100 IP is a Hyper-decoupling capacitor with a Capacitance Multiplication, Series Inductance Nullification, Cybersecurity Enhancement and an Ene ...

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 ...

Figure 1 shows a switching regulator that can generate a lower voltage from a high voltage. In this type of circuit, the bypass capacitor (CBYP) is especially important. It has to support the switched ...
