A 1.3‐GHz Sallen and Key filter, based on a voltage amplifier designed with an original topology, is presented. SiGe realization showed good agreement between simulation and measurement. In particular, the amplifier gain and the filter selectivity can be tuned and Q factors of up to 60 were measured. © 2003 Wiley Periodicals, Inc.
