Abstract

A new charge-based current model for CMOS gates is presented in this paper. The current during a transition consists of three components: one occurs when the input changes and the others exist only when the output changes. So, this model can generate current waveform with negative values, like SPICE. These three components are characterized by triangular functions with four parameters which can be easily obtained after timing simulation. When comparing the results obtained by using SPICE with those by our model, we find agreement, especially on the time points at which maximum current occurs
