This paper describes the use of WEBENCH Coil Designer for generating wireless power transfer PCB inductors for low and medium power portable systems without the need of complex calculations or complex layout design.
The applications of memristors in neuromorphic computing have been extensively studied for its analogy to synapse. To overcome sneak path issue, nonlinear resistive selectors have been introduced to the design of memristor crossbar, enabling a high integration density and robust computing capability. However, the nonlinearity of such selectors also influences the computation accuracy of the vector-matrix...
This article presents two types of circuits used for eddy current sensors capable of detecting objects at large distances (12mm). The first one uses an operational amplifier oscillator with positive feedback and the second one is based on a cross-coupled oscillator with negative transconductance. Both operate at a frequency of 257 kHz. Due to its advantages, such as small silicon area and low-power...
Hydraulic models of the human circulatory system allow simulation of hemodynamics in a standardized setting. In this work we use such a model to compare concurrent control strategies for extra-corporal circulation control. Patients suffering from cardio-vascular diseases under extra-corporal circulation can benefit from an automated regulation. The control task is to keep either the pump flow or the...
In this paper we report a current-to-time converter (CTC) suitable for current sensor monitoring in low power applications. Based on a discrete resistence-to-frequency converter and a Giant MagnetoResistance (GMR) current sensor. Simulations have been done using a quasi-static electrical Verilog-A model for the GMR current sensor. A reduced set of parameters has been extracted to characterize the...
In this paper we present a very new technique for analytical methods which utilize the quartz crystal microbalance (QCM). This is rapid expansion in application and understanding-oriented work. Using the QCM in the liquid phase and applying it to non-rigid over layers have created new experimental opportunities. In research, the most common QCM crystal applications include metal deposition monitors,...
