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, . 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.
