Voltage clamps for protecting low-voltage dc circuits require a new approach to circuit design. Many commonly used voltage clamps were built for systems of 5 V or higher, but lower-voltage systems require distinctive clamping abilities. The use of very-low-voltage precision enhancement-mode MOSFETs play a pivotal role in designing voltage clamps in low-voltage applications. Today’s electronic s...
today the image of a permanent skeletal space of cities affected by some forces or mechanisms is put in time with social-economic development and while imposes a new face and perspective to physical anatomy of cities, and prepares field to changes in content and social- economic structures of cities too. simultaneously with quitting villages in order to settle in cities by villagers, the phen...
This paper presents a low power bandgap reference (BGR) with 573 mV average output voltage and 0.95-V minimum supply voltage. Here, the resistor ratio of two types of resistors that have opposite temperature coefficient (TC) realizes a second-order curvature compensation. In addition, to reduce the supply voltage we adopt a voltage divider, and we also employ proportional to absolute temperatur...
The energy efficiency of systems-on-a-chip can be much improved if one were to vary the supply voltage dynamically at run time. In this paper we describe the synthesis of systems-on-a-chip based on core processors, while treating voltage (and correspondingly, the clock frequency) as a variable to be scheduled along with the computation tasks during the static scheduling step. In addition to des...

A low-voltage DC Microgrid can be used to supply sensitive electronic loads, since it combines the advantages of using a DC supply for electronic loads, and using local generation to supply sensitive loads. A commercial power system which can benefit from using a DC Microgrid is data center. The lower losses due to fewer power conversion steps results in less heat which need to be cooled, and t...
This paper investigates the connection of a single-phase multilevel inverter structure to an existing power grid. The applied voltage source inverter is able to generate a near sinusoidal voltage waveform with an amplitude six times the input voltage by using a single DC input power supply. A proportional-resonant (PR) controller regulates the injected current into the grid. While the EPLL is u...
The explosive growth of battery operated devices has made low-power design a priority in recent years. Moreover, embedded SRAM units have become an important block in modern SoCs. The increasing number of transistor count in the SRAM units and the surging leakage current of the MOS transistors in the scaled technologies have made the SRAM unit a power hungry block from both dynamic and static p...
An ultra-low voltage phase-locked loop (PLL) is demonstrated in standard 130-nm CMOS technology. The PLL employs a novel low-voltage charge-pump circuit which compensates current and leakage mismatches that result in suppressed reference spurs. Its voltage-controlled oscillator is realized with supply-regulated active-loop filter. Our PLL occupies 0.014 mm and consumes 88 μW at 0.4-V supply for...
