In symmetric multilevel inverters, there is a tradeoff between the output quality and the reliability and efficiency of the converter. New asymmetric and hybrid solutions, using different voltages and devices in various parts of the inverter, promise signi ...
This paper presents a continuous voltage and frequency scaling approach achieving lower transition (both energy and time) overheads implied by changing voltage levels, at a very low power dissipation and silicon area cost for multi-processor systems with i ...
Power Factor Corrected rectifiers are a new tendency in development of power supplies. In the last few years, a lot of R&D activities have led to a new category of products for one-phase applications. In this contribution, a new simplified topology is prop ...
This paper presents a new methodology allowing to compare several architectures (or microarchitectures) performing the same function and to select the one presenting the smallest total power consumption under fixed supply voltage (Vdd), threshold voltage ( ...
This article presents a very low-power clock and data recovery (CDR) circuit with 8 parallel channels achieving an aggregate data rate of 20 Gbps. A structural top-down design methodology has been applied to minimize the power dissipation while satisfying ...
We describe a simple and low cost design for generating high voltage pulses using commercially available Ruhmkorff's coils. Our application is the biasing of large area photoconductive switches, used for THz generation, operating at kHz repetition rates. T ...
Growing demand for the solid state meters for power and energy measurement leads to the fully integrated Hall sensor based microsystem solutions. In this paper we describe fully integrated SOI Hall sensor based microsystem for power and energy measurements ...
Conventional RF power amplifiers usually give their maximum efficiency near the maximum output power level. When the output power decreases, the efficiency drops sharply. Deep class AB or B PAs improve their efficiency by a self-adaptation of the current d ...
This paper presents a new hybrid circuit breaker topology based on the use of serial and parallel semiconductors that allows to increase the supply voltage and default current with no arc, and to benefit from a current limitation function. A concrete marin ...
