OverviewUse in analog circuitsUse in digital circuitsGimmick loopParasitic capacitive couplingSee alsoExternal links

In analog circuits, a coupling capacitor is used to connect two circuits such that only the AC signal from the first circuit can pass through to the next while DC is blocked. This technique helps to isolate the DC bias settings of the two coupled circuits. Capacitive coupling is also known as AC coupling and the capacitor used for the purpose is also known as a DC-blocking capacitor. A coupling capacitor''s ability to prevent a DC load from interfering with an AC source is particula…

I2C Design Mathematics: Capacitance and Resistance

The capacitive coupling between the I 2 C signal lines and the ground plane can be significant if the ICs are far from each other, or multiple ICs are on the I 2 C bus. For long runs, separate the I 2 C lines from one another by several trace widths (or place the Vdd and ground traces between the signal traces) to reduce capacitive …
