Residue Amplifier Pipeline Adc
نویسنده
چکیده
This project explores the design of a type of direct-conversion ADC called a Residue Amplifier Pipeline ADC. Direct-conversion ADCs are a class of ADCs that operate at very high speeds, because the input signal is converted to a digital value in a single iteration. Other types of ADCs require many comparison iterations to convert the signal, resulting in much slower conversion times. This design also takes advantage of residue amplifiers to further improve its performance over other direct-conversion ADCs. This paper will explore the theory and design of this ADC.

متن کاملBackground Self-Calibration Algorithm for Pipelined ADC Using Split ADC Scheme
This brief paper describes a background calibration algorithm for a pipelined ADC with an open-loop amplifier using a Split ADC structure. The open-loop amplifier is employed as a residue amplifier in the first stage of the pipelined ADC to realize low power and high speed. However the residue amplifier as well as the DAC suffer from gain error and non-linearity, and hence they need calibration...

This paper proposes a pipeline analog-to-digital converter (ADC) with non-binary encoding technique based on β-expansion. By using multiply-by-β switched-capacitor (SC) multiplying digital-to-analog converter (MDAC) circuit, our proposed ADC is composed by radix-β (1 < β < 2) 1 bit pipeline stages instead of using the conventional radix-2 1.5 bit/1 bit pipeline stages to realize non-binary anal...
