Смысл: The main idea is that decoupling capacitors are essential in digital electronics to mitigate the effects of parasitic inductance in power lines, ensuring stable voltage and signal integrity by providing local energy storage for high-frequency current spikes.
Decoupling capacitors are necessary in digital circuits to provide instantaneous power during signal switching and prevent voltage instability caused by conductor inductance.
Смысл: The main idea is that the physical implementation (topology and placement) of decoupling capacitors is far more critical to power integrity than the specific capacitance value, provided a minimum threshold is met. To minimize noise on the chip, designers must minimize the loop inductance by using top-layer connections and extreme proximity.
Proper decoupling depends more on minimizing parasitic inductance through close placement and top-layer routing than on choosing very large capacitor values.
