In this project a new integrated multi level AC-DC converter is proposed. The proposed converter has two independent controllers. First controller is used to control the input side and the second for the output side. The input controller prevents DC bus voltage from becoming excessive and performs power factor correction and regulates DC bus voltage. The output controller regulates output volta...

Microfluidic devices have applications in chemical analysis, biomedical devices and ink-jets. An integrated microfluidic system incorporates electrical signals on-chip. Such electro-microfluidic devices require fluidic and electrical connection to larger packages. Therefore electrical and fluidic packaging of electro-microfluidic devices is key to the development of integrated microfluidic syst...

This paper presents the design of an A/D converter. The objective of this research is to determine whether a discrete-time approach is the best choice for incorporating the A/D converter into a silicon fully-integrated Hearing-Aid system. In that sense, power consumption, conversion time, and integration area were basic parameters for designing a test chip, which was fabricated and tested. Firs...

This study aims to design analog-to-digital converter based on successive approximations (SAR ADC), with very low power consumption, in an advanced CMOS technology (28 nm), following the industrial methodologies IC. This project was conducted in partnership with Synopsys, operating at a supply voltage of 0.5 V ± 10% with a resolution of 12 bits and 500 kS/s sampling frequency. Keywords— Analog-...

A new partitioning approach integrates the power devices and drive of a high-efficiency synchronous-rectified buck converter for numerous advantages in low-voltage power systems. This approach, coupled with a low-cost voltage-mode controller, improves efficiency by eliminating the dissipative current-sensing resistor and reduces size with a smaller inductor. The resulting converter responds fas...

The task of natural language generation is devided into three major subtasks (see, e.g., Levelt 89]): macro planning (MAP), the elaboration of the communicative intention as a sequence of subgoals and the selection of information to be expressed in order to realize these communicative goals, micro planning (MIP), the further shaping of each speech act to bring it into the format required by the...

We present in this paper a study on the thermal behavior of a square micro coil that will be integrated in a DC-DC micro converter. The first, we calculate the value of inductance. The second, we descript our micro coil; dimensioning, electrical model, and formula of loss. A buck micro converter schematic simulation coupled with ideal and integrated micro coil was presented. This conceptual mod...

Novel compounds termed lipophosphonoxins were prepared using a simple and efficient synthetic approach. The general structure of lipophosphonoxins consists of four modules: (i) a nucleoside module, (ii) an iminosugar module, (iii) a hydrophobic module (lipophilic alkyl chain), and (iv) a phosphonate linker module that holds together modules i-iii. Lipophosphonoxins displayed significant antibac...
