See AVX technical note on how capacitors filter out transients in high speed digital circuits. Link here (PDF) This paper discusses the characteristics of multilayer ceramic capacitors in decoupling applications and compares their performance with other types of decoupling capacitors. A special high-frequency test circuit is described and the results obtained using various types of […]

App note: Decoupling solutions
App note (PDF) from KEMET on different decoupling capacitors for each board power line requirements. Integrated circuit (IC) technology has advanced over time, requiring innovative decoupling solutions that address decoupling needs over the entire power path from the main power supply to the logic gates on the IC. As one follows the path from the […]
On-chip decoupling capacitors
Ralph Doncaster writes: In virtually all of my micro-controller projects, I’ll use 0.1uF ceramic capacitors between Vcc and Gnd. Depending on the power draw of the MCU and inductance on the power lines, they may not be necessary, at a cost of a penny or less each there’s little reason not to use them. I […]
Decoupling capacitors explained
Bertho, winner of the 7400 contest with his Capacitive Sensing, the Hard Way entry, made an excellent tutorial on the use of decoupling capacitors: While enjoying the 7400 contest, it occurred to me that many of the submitted logic designs lacked some of the most elementary safeties to ensure a working result. One of the […]
