Power Supply Patterns of the PCB The power supply wire patterns (VCC and GND patterns) of the PCB should be designed as wide as possible in order to reduce parasitic impedance. 2. Switching Noise In order to reduce switching noise as much as possible, noise limit capacitor must be connected between VCCD and D. GND pins and VCCA and A. GND pins. In this case, the capacitor should be connected to the GND pins side as near as possible.
