Abstract

Scaling the voltage in contemporary digital and mixed-signal systems has shown to be a successful method for lowering both the dynamic power and the leakage power. This has been demonstrated through extensive research. One way that is helpful in the building of ultra-lowpower systems is the decrease of the supply voltage to levels that are either close to or below the threshold voltage. This is one method that can be used. However, operation near or below the threshold slows down digital circuits and diminishes their efficiency, neither of which are properties that are desired in digital circuits. It is required to make use of more than one supply voltage in order to accommodate the various components of the system, which work at different speeds. This article presents the development of a high speed modified wilson current mirror based level shifter for mixed signal systems.
