Abstract :
In integrated circuits, ground bounce is the voltage developed across the inductance of the power supply leads as a result of the current surge through switching gates. It causes distortion of circuit output waveforms that can interfere with testing. This paper describes a simple circuit model that can be used to estimate the ground bounce waveform that appears on both switching and nonswitching outputs of CMOS circuits as a result of ground bounce. The model includes the effects of several circuit parameters on the waveform and has been validated by extensive Spice simulation
