چکیده

This paper describes a technique for digital error correction in pipelined analog-digital converters. It makes use of a slow, high resolution ADC in conjunction with an LMS algorithm to perform error correction in the background during normal conversion. The algorithm will be shown to correct for errors due to capacitor ratio mismatch, finite amplifier gain and charge injection within the same framework.

Optimal fast digital error correction method of pipelined analog to digital converter with DLMS algorithm

In this paper, convergence rate of digital error correction algorithm in correction of capacitor mismatch error and finite and nonlinear gain of Op-Amp has increased significantly by the use of DLMS, an evolutionary search algorithm. To this end, a 16-bit pipelined analog to digital converter was modeled. The obtained digital model is a FIR filter with 16 adjustable weights. To adjust weights o...

Analysis 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...

A digital background calibration technique for pipelined analog-to-digital converters

A new background calibration technique for pipelined analog-to-digital converters is proposed. By dividing the step sizes of the multiplying digital-to-analog converter (MDAC) in a pipeline stages and injecting a random signal into the MDAC, it is possible to calibrate a pipeline stage without interrupting the normal analog-to-digital operation. The calibration can eliminate the nonlinear effec...
