A scheme for a three-level voltage space phasor generation with common-mode voltage elimination is proposed. An open-end-winding induction motor, fed from both ends by two threelevel inverters, which are realised by a cascading two two-level inverter, is used in this configuration. The voltage space vectors of individual three-level inverters, which generate the same commonmode voltage in the i...

A low-power level shifter (LS) using power gating technique is proposed for logic voltage shifting from near/subthreshold to above-threshold voltage domain. Level shifter allow for effective interfacing between voltage domains supplied by different voltage level. Usually conventional level shifter which can shift any voltage level signal to a desired higher level with low leakage current. The n...

Linear AC power supplies can be replaced by their nonlinear switching counterparts due to the lower voltage drops and higher efficiency and power density of switching-mode inverters. Multilevel cascaded H-bridge (CHB) converters are the preferred inverter structure because of modular configuration, control, and protection. The output voltage quality in CHB converters depends on the number of ou...

Level shifters play critical roles in ultra low-voltage circuits and systems. a new low power level shifter (LS) is presented for robust logic voltage shifting from near/sub threshold to above threshold domain. The new circuit combines the multi threshold CMOS technique along with novel topological modifications to guarantee a wide voltage conversion range with limited static power and total en...

Clustered voltage scaling is a power reducing method which does not affect the overall system performance. The main idea is to run gates on a non-critical path by a low-voltage supply. Since low-voltage gates are not able to drive high-voltage gates, level-converters are needed. In order to reduce the number of level-converters, which may cancel out the power savings, they are arranged in a clu...

The one photon absorption (OPA) cross section of a current carrying two-orbital quantum dot (QD) with strong electron-phonon interaction (polaron regime) is considered. Using the self-consistent non-equilibrium Hartree-Fock (HF) approximation, we determine the dependence of OPA cross section on the applied bias voltage, the strength of effective electron-electron interaction, and level spacing ...

Static power dissipation is increases with the scaling in threshold voltage and expected to become important part of total power consumption. In the present work, a new configuration of level shifters for low power application in 0.25μm technology has been presented. The proposed circuits utilize the merit of stacking technique by which there is reduction in leakage power. In this work a new le...
