A Low-Voltage Single-Supply Level Converter for Sub-VTH /Super-VTH Operation: 0. 3V to 1. 2V

A Low-Voltage Single-Supply Level Converter for Sub-VTH /Super-VTH Operation: 0.3V to 1.2V

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...

Near-/Sub-Vth process, voltage, and temperature (PVT) sensors with dynamic voltage selection

A process, voltage and temperature (PVT) sensors with dynamic voltage selection are proposed for environmental management in the ultra-low voltage dynamic voltage and frequency scaling (DVFS) system. The process and voltage (PV) sensors initially monitor the process variation. With known process information, PV sensors can real-time provide voltage variation status. The temperature sensor has s...

Low leakage multi-Vth technique for sequential circuits at transistor level in nanotechnology

Leakage power is the main dominant source of power dissipation for Sub-lOOlJm VLSI circuits. Various techniques were proposed to reduce the leakage power dissipation; one of these techniques is Multi-Threshold voltage. In this paper, the exact and optimal values of Threshold Voltage (Vth) for each transistor of the design are found for any sequential circuit. This is achieved by applying Artifi...

ULS: A Dual-Vth/High-κ Nano-CMOS Universal Level Shifter for System-Level Power Management

Power dissipation is a major bottleneck for emerging applications, such as implantable systems, digital cameras, and multimedia processors. Each of these applications is essentially designed as a analog/mixed-signal systemon-a-chip (AMS-SoC). These AMS-SoCs are typically operated from a single power-supply source which is a battery providing a constant supply voltage. In order to reduce power d...
