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 ...
Steady operating conditions of an extra-high-voltage power line equipped with controlled shunting reactors are considered. The required control of the reactors is shown that enables the permissible levels of voltage at intermediate points of the power line ...
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 ...
The paper presents the programmable multiphase clock generator for switched-capacitor finite impulse response (SC FIR) circular memory filters. The proposed programmable clock circuit enables easy division of such kind of filters into different orders smal ...
This study uses an endogenous switching-regression model to examine the impact of slash-and-burn cultivation practice on the application of commercial fertilizer and pesticides, as well as yields and net returns. The empirical evidence of the study indicat ...
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 ( ...
An implementation of a dynamic supply RF power amplifier (PA) in 0.11 mu m CMOS technology occupying a total area of 1.35mm(2) is presented. Two-tone measurement results at 2.4 and 5.2GHz show that the system can deliver over 16dBm linear output power with ...
Integrating visual and inertial sensors has become a common practice in navigation due to the increase in computer power, in algorithms advancement and in sensor improvements. One of the problems yet to be solved is the Simultaneous Localisation And Mappin ...
The control of the current, position and shape of an elongated cross-section tokamak plasma is complicated by the so-called instability of the current vertical position. Linearized models all share the feature of a single unstable eigenmode, attributable t ...
In this work, MOS Current Mode Logic (MCML) is analyzed for low power, low noise, mixed signal applications demanding high security such as embedded cryptographic processors and smart cards. We emphasize the possible extension of MCML gate usage for low sp ...
