Abstract :
This paper presents a technique for programmable switched-capacitor (SC) filters based on periodical nonuniform individual sampling (PNIS) of each SC structure in the filter. It is shown how very wide range of programmability in all circuit parameters can be obtained, whereas the dynamic range degradation is kept minimum. Experimental results obtained from a 1.2 μm CMOS second-order SC filter are given
