ABSTRACT:
A method of power consumption reduction in integrated circuits comprising extensive use of differential signaling within said circuits. Differential signaling comprises a pair of coupled, symmetrically opposite and operatively dependent electronic signals each driven by voltages of the same magnitude, but of opposite polarity with respect to a common ground. The drive voltages of each signal are of relatively low potential as compared to the core operating voltage of present day devices. The low-voltage pair of signals tends to create offsetting fields of electromagnetic interference from the flow of current within their respective conductors which tends to minimize inductive effects (and therefore corruption of signals) in adjacent signal lines. Differential signaling replaces all or as many single-end signals as possible throughout the device resulting in relatively lower power usage as compared to present devices.
