Abstract
We propose an opposite-phase scheme for peak current reduction. The basic idea is to divide the clock buffers at each level of the clock tree into two sets: one half of the clock buffers operate at the same phase as the clock source, and the other half of the clock buffers operate at the opposite phase to the clock source. Consequently, our approach can effectively reduce the peak current of the clock tree. The method enables the opposite-phase scheme to combine with the electronic design automation (EDA) tools that are commonly used in modern industries.
