Abstract :
This paper presents a programmable switched-current filter based on a universal wave filter structure which allows obtaining different filtering functions from a same low-pass reference filter, without altering the global circuit topology. A first circuit implementing a low-pass and a band-pass Chebyschev filter has been designed and fabricated in the ES2 1.5¿m CMOS process. The experimentally measured results are reported.
