UNIVERSAL RC-ACTIVE NETWORK USING CCII+

Josef Čajka - Dalibor Lindovský

   Recently, a useful universal four-port network using three second-generation conveyors CCII+ was published, [1]. Modifying this network, all filter types (including allpass filter) can be obtained. All these second-order circuits (biquads) are low-sensitive to variations in circuit parameters. We will show that the same circuits can be built from two equivalent autonomous general networks.
