Design of Multi Threshold (Multi Vth) Level Converters for Block Interfaces

چکیده
High-performance and low-power are the two main criteria in modern digital design. Level converters are important to transfer low voltage input swing signal among the circuits operating at different voltages to get high voltage output swing signal. Previously feedback level converters suffer from short circuit power and long propagation delay. Multi Vth level converters and multiple supply voltages assignment are used to reduce the power dissipation, propagation delay. The blocks operate at high speed utilizes high supply voltages and blocks operate at low speed utilizes lower supply voltage. To interface these blocks, level converters can be used. Based on this survey a new low power and high performance level converters are proposed.

Digital sub-threshold circuits are significant for ultra-low power (ULP) applications. Operating circuits at ultra-low voltage levels leads to the less power per operation. An optimized method is separating the logic blocks based on performance requirement and utilizing multiple-supply voltage (VDD) for each blocks. In order to prevent an enormous static current in these multi-VDD circuits, vol...
