Abstract :
An integrated 18th-order frequency symmetrical switchedcapacitor (SC) band-pass filter is described that has been realized according to the approach involving the use of voltage inverter switches (VIS\´s) in form of recharging devices. The filter has been implemented in a standard CMOS technology. It has been conceived for use as "channel filter" in modulation schemes for PCM/FDM and audio/FDM conversion. Starting from a high-pass filter as reference filter, the SC filter is designed as pseudo- 
-path filter, with 
. The application of the pseudo- -path principle has lead to a substantial amount of saving in hardware.
