TLDR
In this article, a unified view of sampled-data charge-conserving circuits for analog-to-digital (A/D) and digital-toanalog (D/A) converters and audio frequency filters is presented.Abstract:
Precision analog integrated circuits may be realized using MOS transistors and accurately ratioed MOS capacitors. Compatibility with high-density digital MOS circuits leads to the possibility of fully Integrated subsystems employing both analog and digital circuitry. This paper presents a unified view of sampled-data charge-conserving circuits for analog-to-digital (A/D) and digital-to-analog (D/A) converters and audio frequency filters.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.

All-MOS charge-redistribution analog-to-digital conversion techniques. II
TL;DR: This second paper describes a two-capacitor successive approximation technique which, in contrast to the first, requires considerably less die area, is inherently monotonic in the presence of capacitor ratio errors, and which operates at somewhat lower conversion rate.

MOS sampled data recursive filters using switched capacitor integrators
TL;DR: A new technique to analog sampled data filtering is presented which can be fully integrated using MOS technology, and advantages of this new approach are reduced circuit complexity, low sensitivity to coefficient variations, and efficient utilization of silicon area.

Journal ArticleDOI
Analog sample-data filters
TL;DR: An analogue sample-data filter exactly equivalent, in the sample- data limit, to a simple RC low pass filter is demonstrated and the basic concept is extended to apply to high-pass and to very-high-Q bandpass filters.
