The use of switched capacitors as wide-range, programmable resistive elements in spatially extensive artificial dendritic trees (ADT's) is described. We show that silicon neuro-morphs with ADT's can produce impulse responses that last millions of times longer than the initiating impulse and that dynamical responses are tunable in both shape and duration over a wide range. The switched-capacitor...

We propose a universal MEMS technology platform for fabricating integrable passive components for radio frequency (RF) integrated circuits. This platform is based on a novel surface-micromachined MicroElevator by Self-Assembly (MESA) techque. Both high-Q inductors and variable capacitors can be realized by the MESA technology. A surface-micromachined spiral inductor that is raised by 250 pm abo...

This paper proposes a shared-capacitor charge-sharing ROM (SCCS-ROM). The SCCS-ROM reduces the swing voltage using the charge-sharing technique of the charge-sharing ROM (CSROM) [4]. Although the CS-ROM needs three small capacitors per output, the SCCS-ROM shares the capacitors so that it needs only three capacitors. The SCCS-ROM implements the capacitors using dummy bit lines. This not only in...

-Multilayer ceramic chip capacitor CDR-05 (MIL part number) is one of the most used parts in ISRO’s satellite program. Cracks evolved in ceramic chip capacitors CDR-05 (size: 1825and dielectric: X7R) of two different makesduring soldering process are studied in this paper. It has been observed that CDR-05 capacitors of one particular make (Manufacturer-A) more prone to crack during soldering on...

The paper presents a virtual instrument developed for capacitors bank dimension as to compensate the reactive power and to raise the power factor in power systems. The mathematical support of the software is accurately described in papers 2 section, along with the negative effects of a low power factor and the advantages of using capacitors banks for reaching the neutral power factor. The 3 sec...

We previously showed that microparts can be fed along a saw-toothed surface using simple planar symmetric vibrations. Microparts move forward because they adhere to the saw-toothed surface asymmetrically. We used saw-toothed silicon wafers fabricated by a dicing saw applying bevel type blades. We then studied the movement of 2012-type capacitors (size:2.0× 1.2× 0.6 mm, weight:7.5 mg) and 0603-t...

A β-ray detecting nuclear quadrupole resonance system has been developed at NSCL/MSU to measure ground-state electric quadrupole moments of short-lived nuclei produced as fast rare isotope beams. This system enables quick and sequential application of multiple transition frequencies over a wide range. Fast switching between variable capacitors in resonance circuits ensures sufficient power deli...

Title of dissertation: MOISTURE IN MULTILAYER CERAMIC CAPACITORS Daniel Noel Donahoe, Doctor of Philosophy, 2005 Dissertation directed by: Professor Michael G. Pecht Department of Mechanical Engineering When both precious metal electrode and base metal electrode (BME) capacitors were subjected to autoclave (120 oC/100 % RH) testing, it was found that the precious metal capacitors aged according...

Recently, a previous contributor showed how the delta-wye conversion may be applied to find the equivalent capacitance of five capacitors arranged in a bridge configuration. In fact, that contributor gave an algorithm for this purpose which showed that the equivalent capacitance depends upon all five capacitors. However, in this paper, we point out that there is a special case where the equival...

AbstrAct: This paper presents a new approach of modelling, design, and characteristics of variable radio frequency micro-electromechanical system (RF-MEMS) capacitor integrated on leaky wave antenna (LWA) operating at 94 GHz. This antenna was implemented on grounded coplanar waveguide (CPW). A 2D distributed mathematical model for the capacitor has been developed along this paper; we formulate ...
