Electromagnetic Noise Reduction Slide 53

For example, pass-through current – pulse current that flows directly from Vcc to GND – is a primary cause of high-frequency noise radiated from the device. By adding a control circuit that shifts the timing of the switching signals that turn the P-channel and N-channel transistors on and off, they can eliminate the pass-through current in these transistors.
