Input-Dependent Integral Nonlinearity Modeling for Pipelined Analog-Digital Converters
Integral nonlinearity (INL) for pipelined analog– digital converters (ADCs) operating at RF is measured and characterized. A parametric model for the INL of pipelined ADCs is proposed, and the corresponding least-squares problem is formulated and solved. The INL is modeled both with respect to the converter output code and the frequency stimuli, which is dynamic modeling. The INL model contains...
متن کاملPipelined Analog-Digital Converters Integral Nonlinearity Modeling for Post-Correction
An input-dependent integral nonlinearity (INL) model is developed for pipeline ADC post-correction. The INL model consists of a static and dynamic part. The INL model is subtracted from the ADC digital output for compensation. Static compensation is performed by adjacent sets of gains and offsets. Each set compensates a certain output code range. The frequency content of the INL dynamic compone...
متن کاملAnalysis of Integral Nonlinearity in Radix-4 Pipelined Analog-to-Digital Converters
In this paper an analytic approach to estimate the nonlinearity of radix-4 pipelined analog-to-digital converters due to the circuit non-idealities is presented. Output voltage of each stage is modeled as sum of the ideal output voltage and non-ideal output voltage (error voltage), in which non-ideal output voltage is created by capacitor mismatch, comparator offset, input offset, and finite ga...
متن کاملPost-Correction of Pipelined Analog-Digital Converters based on Input Dependent Nonlinearity Modeling_revised version.dvi
The integral nonlinearity (INL) is used for the post-correction of analog-digital converters (ADCs). An inputfrequency-dependent INL-model is developed for the postcorrection. The model consists of a static term that is dependent on the ADC output code and a dynamic term that has an additional dependence on the input frequency. The concept of ADC digital output post-correction by INL is first i...
متن کاملModeling Memory Errors in Pipelined Analog-to-digital Converters
Switched-capacitor implementations of pipelined ADCs contain several sources of memory errors, including capacitor dielectric absorption/relaxation, incomplete stage reset at high clock rates, and parasitic capacitance effects when op amps are shared between subsequent pipeline stages. This paper describes these sources of memory errors and presents a unified model for their effect. The depende...
