TLDR
Improved computer-aided analog-to-digital converter (ADC) characterization methods based on the code density test and spectral analysis using the fast Fourier transform are described.Abstract:
Improved computer-aided analog-to-digital converter (ADC) characterization methods based on the code density test and spectral analysis using the fast Fourier transform are described. The code density test produces a histogram of the digital output codes of an ADC sampling a known input. The code density can be interpreted to compute the differential and integral nonlinearities, gain error, offset error, and internal noise. Conversion-rate and frequency-dependent behavior can also be measured.read more

A 15-b 1-Msample/s digitally self-calibrated pipeline ADC
TL;DR: In this paper, a 15-b 1-Msample/s digitally self-calibrated pipeline analog-to-digital converter (ADC) is presented with a radix 1.93, 1 b per stage design, which accounts for capacitor mismatch, comparator offset, charge injection, finite op-amp gain and capacitor nonlinearity contributing to DNL.

On the use of windows for harmonic analysis with the discrete Fourier transform
TL;DR: A comprehensive catalog of data windows along with their significant performance parameters from which the different windows can be compared is included, and an example demonstrates the use and value of windows to resolve closely spaced harmonic signals characterized by large differences in amplitude.

An integrated-circuit-based speech recognition system
H. Murveit,R. Brodersen +1 more
TL;DR: A high-performance, flexible, and potentially inexpensive speech recognition system that can compare an input word with 1000-word templates and respond to a user within 1-4 s demonstrates that computational complexity need not be a major limiting factor in the design of speech recognition systems.

A High-Resolution Error Plotter for Analog-to-Digital Converters
TL;DR: An automatic error plotting system for analog-to-digital converters (ADC's) which measures the static errors of the device under test at every quantization band edge (QBE) and displays them in graphical form and shows the ability of the system to display common types of ADC errors and to display error signatures that often point to specific ADC problems.
