Abstract
The following chapter includes all the new circuit techniques related to frequency selective stages. After reviewing the Log companding principle of operation, the generalization for the MOS transistor is presented. Based on these results, different types of CMOS basic building blocks for arbitrary Log filters are proposed in conjunction with a compact synthesis methodology. This research is extended to all-MOS implementations for their integration through digital CMOS technologies. Finally, some filter cases and design examples are presented as demonstrators.
