A Digital Background Correction for Dac Nonlinearities in Lowpass and Bandpass Delta-sigma Modulators - Theory and Implementation
نویسندگان
چکیده
In this paper we review a background digital DAC linearization technique for Delta-Sigma analog-to-digital converters (∆Σ ADCs). A description of the theory behind this technique, details on a modulator implementation, measurement results, and finally an outlook for enhancing this technique for bandpass ∆Σ ADCs is provided. The technique has been successfully implemented in hardware and we here give a review on our work from early system level ideas for the background error estimation to measurements on real hardware.

A new technique is proposed to eliminate the nonlinear error of a multibit digital-to-analog converter (DAC) used in a sigma-delta modulator where the solidity of multibit DAC against the clock jitter is reserved. By using dual quantization, this technique reduces the bit length of DAC to one bit and consequently eliminates its nonlinear error. A lowpass finite impulse response (FIR) filter wit...

An efficient means for constructing a narrow bandpass filter for an analogto-digital converter based on a bandpass sigma-delta modulator is presented. It is shown that the filter can be made with very simple hardware, comparable to that required by an analog-to-digital converter using standard lowpass sigma-delta modulation. Introduction Bandpass sigma-delta modulation [1] is a variant of the m...
