The book "Methodology for the Digital Calibration of Analog Circuits and Systems" offers a comprehensive analysis and methodology for the digital calibration of analog circuits and systems. It demonstrates how the strict design constraints in analog engineering can be relaxed to achieve high-precision systems even with less powerful components. The authors, Marc Pastre and Maher Kayal, guide the reader through existing compensation techniques for imperfections in analog circuits and present a detailed examination of the M/2+M sub-binary digital-to-analog converter. The methodology includes the detection and correction of imperfections, as well as the introduction of a simulation tool that allows for transparent simulation of analog circuits with automatic compensation blocks. The book addresses three specific applications that illustrate the practical implementation of the proposed methodology.
