Abstract
A data bus charge-sharing technique for integrated circuit devices may be implemented utilizing two voltage regulators to generate constant voltages VEQand VEQ, which are in the particular exemplary implementation disclosed, approximately 0.9 times a supply voltage VCC and 0.1 times VCC, respectively. One set of signals switches between VCC and VEQ, and a second set of signals switches between VEQand 0V. Charge-sharing between the two sets of signals is accomplished by the unique configuration of the voltage regulators.
