To effectively integrate bacteriorhodopsin (bR) with micro electromechanical systems (MEMS) and nano electromechanical systems (NEMS) devices, it is critical to know the electrical properties of the material and to understand how it will affect the functionality of the device. Inductance, capacitance and resistance (LCR) measurements can be used to determine material characteristics, such as permittivity,...
An on-chip buck converter with 3D chip stacking is proposed and the operation is experimentally verified. The manufactured converter achieves a maximum power efficiency of 62% for an output current of 70mA with a switching frequency of 200MHz and a 2x2mm on-chip LC output filter in 0.35mum CMOS. The use of glass epoxy interposer to increase the maximum power efficiency up to 71.3%, and the power efficiency...
A technique for extraction and optimization of silicon substrate parameters is presented. The parameters are optimized to get the best fit between measured and simulated S-parameters for passive elements. Test structures were fabricated in a SiGe:C process with 5 metallization layers. The measurements were performed on-wafer. Loss and relative permittivity ??r of each insulation layer is extracted...
In order to analyze and interpret a.c. data obtained from dielectric measurements of insulator materials, attemps have been made to understand the a.c. behaviour of simple R.C. circuits, so than an appropriate simulation can be made. The plots and some data from insulator materials are presented including the well known temperature and frequency dependance of the resistive component. The analysis...
