An IC Amplifier User’s Guide to Decoupling, Grounding, and ...

Figure 3 illustrates three possible configurations for nega-tive supply decoupling. In 3a, the dotted line shows the negative signal current path through the decoupling and along the ground line. If the load “ground” and decoupled “ground” actually join at the power supply, the “glitch”
