Design of high-speed adaptive parallel multi-level decision feedback equalizerXiang, Yihai 26 February 1997 (has links)
Multi-level decision feedback equalization (MDFE) is an effective technique to remove inter-symbol interference (ISI) from disk readback signals, which uses the simple architecture of decision feedback equalization. Parallelism which doubles the symbol rate can be realized by setting the first tap of the feedback filter to zero.
A mixed-signal implementation has been chosen for the parallel MDFE, in which coefficients for the 9-tap feedback filter are adapted in the digital domain by 10-bit up/ down counters; 6-bit current mode D/A converters are used to convert digital coefficients to differential current signals which are summed with the forward equalizer (FE) output, and a flash A/D is used to make decisions and generate error signals for adaptation.
In this thesis, a description of the parallel structure and the adaptation algorithm are presented with behavioral level verification. The circuit design and layout were carried out in HP 1.2um n-well CMOS process. The design of the high-speed counter and the current-mode D/A are discussed. HSPICE simulations show that a symbol rate of 100Mb/s for the feedback equalizer is readily achieved. / Graduation date: 1997

Design of high-speed low-power analog CMOS decision feedback equalizersSu, Wenjun 08 July 1996 (has links)
Decision feedback equalizer (DFE) is an effective method to remove inter-symbol
interference (ISI) from a disk-drive read channel. Analog IC implementations of DFE
potentially offers higher speed, smaller die area, and lower power consumption when
compared to their digital counterparts.
Most of the available DFE equalizers were realized by using digital FIR filters
preceded by a flash A/D converter. Both the FIR filter and flash A/D converter are the
major contributers to the power dissipation. However, this project focuses on the analog
IC implementations of the DFE to achieve high speed and low power consumption. In
other words, this project gets intensively involved in the design of a large-input highly-linear
voltage-to-current converter, the design of a high-speed low-power 6-bit
comparator, and the design of a high-speed low-power 6-bit current-steering D/A
converter.
The design and layout for the proposed analog equalizer are carried out in a 1.2
pm n-well CMOS process. HSPICE simulations show that an analog DFE with 100 MHz
clock frequency and 6-bit accuracy can be easily achieved. The power consumption for
all the analog circuits is only about 24mW operating under a single 5V power supply. / Graduation date: 1997

Predictive control using feedback- : a case study of an inverted pendulumBarrett, Spencer Brown 17 August 1995 (has links)
Vision is a flexible, non-contact sensor that can be used for position feedback in
closed-loop control of dynamic systems. Current vision systems for industrial
automation provide low sample rates and large sample delays relative to other types of
position sensors. Poor sample rates and sample delays are a result of the vast volume of
data that must be collected and processed by the vision system. A predictive visual
tracker can help compensate for some of the deficiencies of current industrial vision
systems. The objectives of the present research are to demonstrate that vision is a useful
feedback sensor and prediction can be used to improve performance by compensating for
the feedback delay of the vision system.
An inverted pendulum was stabilized using a vision sensor as feedback to a state-feedback
controller. The vision data was run through a d-step ahead predictor to
compensate for the vision system delays. The system was simulated in Mat lab and an
actual physical system was used to test the performance of the control system.
The inverted pendulum provides a good test-bed for studying predictive control
using vision feedback. The pendulum will fall without the constant adjustment of the
cart position. The adjustment of the cart by the controller is delayed because of latency
and quantization errors in vision feedback. The better the controller is able to
compensate for delays and quantization errors, the greater its ability to stabilize the
inverted pendulum. / Graduation date: 1996
