Abstract :
This paper presents a low-power multiple-valued VLSI based on two current-source control techniques. The first technique is a current-source control based on valid data signal detection. The other technique is a current-source control such that current sources are turned off within a clock cycle after a logic operation completion signal is detected. In a multiple-valued reconfigurable VLSI, power consumption of a cell with the low-power technique is reduced to 49% in comparison with that of the cell without the low-power technique, when the operating frequency is 500MHz, and the utilization ratio of the cell is 25%.
