  • A SECOND GENERATION CURRENT CONVEYOR (CCII) HAVING A TUNABLE FEEDBACK NETWORK
    Publication number: 20210408988
    Abstract: A Second-Generation Current Conveyor (CCII) has a three-port network with ports designated as X, Y, and Z, wherein the CCII includes a tunable feedback network. The tunable feedback network may be provided between at least two of the ports, e.g., ports Z and Y. The tunable feedback network may comprise a tunable RC (Resister-Capacitor) network which may be provided by solid-state components such as a MOS (Metal-Oxide Semiconductor) device or a MOS resistor (for the resistive element) and a varactor (for the capacitive element).

  • Second-order all-pass network comprising CCIIs
    Patent number: 10911025
    Abstract: A second-order all-pass network has at least three Second Generation Current Conveyors (CCIIs). A network input is connected or connectable to a Y port of a first CCII, a Z port of the first CCII is connected to a Y port of a second CCII, an X port of the first CCII is connected to a Y port of a third CCII, and a network output is connected or connectable, directly or indirectly, to a Z port of the second CCII. The X port of the first CCII is connected via a first network element to ground, the Z port of the first CCII is connected via a second network element to ground, an X port of the third CCII is connected via a third network element to ground, and an X port of the second CCII is connected via a fourth network element to ground.
