Optimization of Quantized Analog Signal Processing Using Genetic Algorithms and μ-Law

open access: yesIEEE Open Journal of Circuits and Systems, 2022
Digital mismatch calibration for quantized analog (QA) signal processing is proposed for the first time. Since the proposed calibration mechanism does not require uniform QA slicer levels, non-uniform quantization can be applied to improve the system ...
