A Fully Digital, Energy-Efficient, Adaptive Power-Supply Regulator
نویسندگان
چکیده
A voltage scaling technique for energy-efficient operation requires an adaptive power-supply regulator to significantly reduce dynamic power consumption in synchronous digital circuits. A digitally controlled power converter that dynamically tracks circuit performance with a ring oscillator and regulates the supply voltage to the minimum required to operate at a desired frequency is presented. This paper investigates the issues involved in designing a fully digital power converter and describes a design fabricated in a MOSIS 0.8m process. A variable-frequency digital controller design takes advantage of the power savings available through adaptive supply-voltage scaling and demonstrates converter efficiency greater than 90% over a dynamic range of regulated voltage levels.

There is a need for IC chips that can support very high input/output (I/O) bandwidths. The key to high bandwidth is high per-pin I/O data rate and low power operation to enable a large number of pins to be integrated.

Abstract: Energy-efficient design for self-timed circuits is investigated. Null convention logic is employed to construct speed-independent self-timed circuits. For error-free computation, the supply voltage automatically tracks the input data rate so that the supply voltage can be kept as small as possible while maintaining the speed requirement. For error-tolerable computation, such as soft d...
