This lecture presents the different system-level and block-level techniques that allow efficient sensor interfacing with A/D conversion. In particular, open- and closed-loop topologies are presented, as well as voltage- and charge-mode readout interfaces. Several examples demonstrate the application of the techniques proposed. Finally, a very efficient technique for self-calibration is presented: Sub-binary radix DACs.
