This paper proposes a novel, tunable AC coupled capacitive feedback amplifier, exhibiting an ultra-low high pass corner frequency. is accomplished by actively boosting the output resistive value of MOS transistor in weak inversion. The circuit based on more general architecture, recently proposed authors, and analyzed terms its capability to achieve frequency operation, DC performance, noise. t...

This paper demonstrates the phase imbalanced series capacitive compensation concept to enhance power system dynamics as it has the potential of damping power swing as well as sub synchronous resonance oscillations. A scheme for a phase imbalanced capacitive compensation is shown. It is a “hybrid” series compensation scheme, where the series capacitive compensation in one phase is created using ...

In this paper, a fast automatic precision approaching system is developed for electrochemical nanofabrication using visual and force-displacement sensing. Before the substrate is fabricated, the template should approach the substrate accurately to establish the initial gap between the template and substrate. During the approaching process, the template is first quickly moved towards the substra...

Our long-term goal is to improve adherence to a home-based isometric program for rehabilitation of knee osteoarthritis (OA) using a force-biofeedback device (Isopad). Our goal for Phase I was to design and evaluate an Isopad-based program in a supervised clinical setting. Our subjects were five patients with knee OA of Kellgren stage II or greater. A capacitive force sensor was tested for accur...

In this work, a design of wireless system for multi-sensors monitoring has been presented. The main purpose of this research is to develop an efficient telemetry system for measuring water pressure and temperature signals. The system reads data from two types of sensors, temperature (resistive) and pressure (capacitive). Anderson circuit configuration has been used for the resistive sensor, sin...
