Abstract: Applying multiple supply voltages (multi- VDD) is an effective technique for reducing the power consumption without reducing speed in an integrated circuit (IC). In order to transfer signals among the circuits operating at different supply voltages specialized voltage level converters are required. Two new multi threshold voltage (multi-VTH) level converters are proposed in this paper. The proposed level converters are compared with the level converters in [7], for operation at different supply voltages. When the level converters are individually optimized for minimum power consumption and propagation delay, the proposed level converters offers significant power saving and speed is enhanced as compared to the level converter in [7] of same technology.
Keywords: High-performance, multiple supply voltages, multiple threshold voltages, power efficiency, voltage level converters.
