In this paper, an incremental Analog-toDigital Converter (ADC) designed as part of the signalconditioning circuitry for tissue impedance measurement system is presented. Continuous-time design techniques has been used and a modified implementation of the conversion algorithm, with respect to its discrete-time counterpart, has been developed. To reduce the influence of the no-idealities, analog ...

Signal degradation and an array size dictated by the number of available interconnects are the two main limitations inherent to standalone microelectrode arrays (MEAs). A new biochip consisting of an array of microelectrodes with fully-integrated analog and digital circuitry realized in an industrial CMOS process addresses these issues. The device is capable of on-chip signal filtering for impr...

INTRODUCTION Every imaging system starts with an image sensor. The signal from the sensor must be processed in the analog domain, converted to digital, and further processed in the digital domain. This allows the image to be analyzed, manipulated, and enhanced, prior to storage, display, transmission, and/or further processing. Imaging applications typically involve three chips—an image sensor,...

An implementation of Manchester coding is being described in this paper. Manchester coding technique is a digital coding technique in which all the bits of the binary data are arranged in a particular sequence. The Intersil HD-15530 is a high performance CMOS device intended to service the requirements of MlL-STD-1553 and similar Manchester II encoded, time division multiplexed serial data prot...

Aligning liquid crystal (LC) molecules into spatially non-uniform orientation patterns is central to the functionalities of many emerging LC devices. Recently, we developed a new projection photopatterning technique by using plasmonic metamasks (PMMs), and demonstrated high-resolution and high-throughput patterning of molecular orientations into arbitrary patterns. Here we present comparisons b...

The modular power converter designed for the Monterey Accelerated Research System (MARS), and recently successfully tested by the Jet Propulsion Laboratory (JPL) and the University of Washington, is a significant milestone in the development of regional cabled observatories. The ability to transmit up to 10kW reliably over long distances using 10kV direct current (dc) and convert it to a more u...

This thesis focuses on a digital Built-in Self-Test (BIST) approach to perform specification oriented testing of the analog portion of a mixed-signal system. The BIST utilizes a direct digital synthesizer (DDS) based test pattern generator (TPG) and a multiplieraccumulator (MAC) based output response analyzer (ORA) to stimulate and analyze the analog devices under test, respectively. This appro...
