Reconfigurable filter structure designed for different positioning systems

Second and fourth order reconfigurable filter structure implemented with second generation current controlled current conveyor is presented in this paper. Reconfigurable filter structure is widely used on the basis of the encrypted communication, cognitive radio and software defined radio systems. The designed filter is applied to the global positioning systems (GPS, GLONASS, Beidou, GNSS and Galileo) to be processed on a single discrete filter. The layout and the post - layout simulations is verified for the designed filter. AMS0.18μm process parameters and CADENCE environment are used for the simulations.
