The Power Of Logic

By Barry Pangrle CMOS logic has been dominant since nMOS gave way back in the 1980s. Dynamic logic, like domino, has seen its application in high-speed and often hand-crafted datapath circuits. The potential energy efficiency of operating at near-threshold voltage is very enticing but having to deal with variability issues has made engineers reluctant to try to do more at lower voltages. The q... » read more
