Abstract - Neglecting the current due to voltage glitches in CMOS circuits can lead to large errors in the estimated power and ground bus currents. What little glitch-related research has been reported, has focused on glitch voltage analysis for power estimation. We present a model for the glitch current and time in a CMOS 2-input NOR gate. It is an empirical model which exploits the linear dependence of both quantities on the input signal overlap time. The model is accurate to within 15% of HSPICE with the level-3 MOSFET model. When used with a previously reported model for the analysis of currents due to complete logical transitions, the speed is two to three orders faster than HSPICE.
