A Fully-Integrated Adaptive Temperature-Compensating Ethernet Equalizer for Automotive Applications

Department of Electrical EngineeringIn this paper, the Ethernet equalizer that compensates automotive temperature range is presented. More and more, the communications in automotive are important because of many electronics in the vehicle. Ethernet protocol can be candidate of automotive communications. However it should satisfy AEC-Q100. For meeting AEC-Q100, it should have an operational temperature range from -40 degree to 150 degree. This paper proposes the Ethernet equalizer that can recover the data until 100m CAT-5 cable adaptively at -40 degree to 150 degree. For supporting the wide temperature range, feedback system is used. The proposed equalizer has 31.25 MHz bandwidth and a fully-differential structure. The proposed automotive Ethernet equalizer is implemented in a Hynix 0.13 um BCDMOS technology.ope

Introduction to the special issue on the 36th European Solid-State Circuits Conference (ESSCIRC)

The 22 papers in this special issue were originally presented at the 2010 European Solid-State Circuits Conference (ESSCIRC). The conference was jointly organized with the European Solid-State Device Research Conference and held September 14-16 in Seville, Spain. Papers cover the traditional ESSCIRC topics of analog circuits, digital circuits, data converters, sensors and imagers, and communications and RF circuits. Energy harvesting and biomedical circuits were also within ESSCIRC 2010 topics and are represented in this issue

Experimental Verification Of A Diode-Clamped Resonant Gate Driver Network

The objective of this project is to perform analysis on the overall performance and efficiency of converter by doing experiment. The duty ratio, resonant inductor value and the dead time are the parameters that influence on the switching losses and other losses in the gate drivers. From the previous work which is done through simulation, it is found that optimized value of inductor is 9nH. By doing experiment work, to maximize capability of RGD circuit, the varied duty ratio by constructing PWM generation network, fixed inductance value of almost 9nH and varied the dead time has been chosen

A Low-Power Wireless Multichannel Microsystem for Reliable Neural Recording.

This thesis reports on the development of a reliable, single-chip, multichannel wireless biotelemetry microsystem intended for extracellular neural recording from awake, mobile, and small animal models. The inherently conflicting requirements of low power and reliability are addressed in the proposed microsystem at architectural and circuit levels. Through employing the preliminary microsystems in various in-vivo experiments, the system requirements for reliable neural recording are identified and addressed at architectural level through the analytical tool: signal path co-optimization. The 2.85mm×3.84mm, mixed-signal ASIC integrates a low-noise front-end, programmable digital controller, an RF modulator, and an RF power amplifier (PA) at the ISM band of 433MHz on a single-chip; and is fabricated using a 0.5µm double-poly triple-metal n-well standard CMOS process. The proposed microsystem, incorporating the ASIC, is a 9-channel (8-neural, 1-audio) user programmable reliable wireless neural telemetry microsystem with a weight of 2.2g (including two 1.5V batteries) and size of 2.2×1.1×0.5cm3. The electrical characteristics of this microsystem are extensively characterized via benchtop tests. The transmitter consumes 5mW and has a measured total input referred voltage noise of 4.74µVrms, 6.47µVrms, and 8.27µVrms at transmission distances of 3m, 10m, and 20m, respectively. The measured inter-channel crosstalk is less than 3.5% and battery life is about an hour. To compare the wireless neural telemetry systems, a figure of merit (FoM) is defined as the reciprocal of the power spent on broadcasting one channel over one meter distance. The proposed microsystem’s FoM is an order of magnitude larger compared to all other research and commercial systems. The proposed biotelemetry system has been successfully used in two in-vivo neural recording experiments: i) from a freely roaming South-American cockroach, and ii) from an awake and mobile rat.Ph.D.Electrical EngineeringUniversity of Michigan, Horace H.
