High Speed Fast Transient Digitizer Design And Simulation, Eric Clark Monahan

UNLV Theses, Dissertations, Professional Papers, and Capstones

In microelectronics, analog-to-digital converters (ADCs) are used as interfaces to convert analog inputs into discrete time or digital values that can be read via microcontrollers. As speed requirements and processing times in electronics continue to increase, high speed ADCs are increasingly critical components in the design of application-specific integrated circuits (ASICs). However, high speed ADCs introduce quantization error and are inefficient relative to size, cost, and power dissipation when compared to a High Speed Fast Transient Digitizer (HSFTD).

This thesis presents the design, layout, and simulation of a HSFTD designed to sample, in time at a fast rate, a high-speed …

Design, Fabrication And Testing Of Monolithic Low-Power Passive Sigma-Delta Analog-To-Digital Converters, Angsuman Roy

UNLV Theses, Dissertations, Professional Papers, and Capstones

Analog-to-digital converters are critically important in electronic systems. The

difficulty in meeting high performance parameters increases as integrated circuit design

process technologies advance into the deep nanometer region. Sigma-delta analog-todigital

converters are an attractive option to fulfill many data converter requirements.

These data converters offer high performance while relaxing requirements on the precision

of components within an integrated circuit. Despite this, the active integrators found within

sigma-delta analog-to-digital converters present two main challenges. These challenges are

the power consumption of the active amplifier and achieving gain-bandwidth necessary for

sigma-delta data converters in deep nanometer process technologies. Both of these

challenges …

Fast Transient Digitizer And Pcb Interface, Kevin Thomas Buck

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis outlines the design, layout and characterization of an application specific integrated circuit (ASIC) and a printed circuit board (PCB) designed to discretize an input signal and read out the data at a user desired interval to replicate the input signal at a lower frequency or pulse rate with no quantization error. The ASIC for this task utilizes 128 individual capacitive storage cells to capture data at approximately 200 ps intervals, thus the chip can capture approximately 25 ns of an input signal. The read out rate can be adjusted to the desired rate by the user by changing …
