  • New RC-Active Networks Using Current Conveyors 

    Vrba, K.; Cajka, J.; Zeman, V. (Společnost pro radioelektronické inženýrství, 1997-06)
    Two novel autonomous networks containing current conveyors are presented. The design of second-order oscillators and frequency filters based on the above general networks is described. The Q-factor of the circuits designed ...
  • Practical Aspects of the Transmission Line Stub Matching in Microstrip 

    Novak, S. (Společnost pro radioelektronické inženýrství, 1997-06)
    While designing microwave circuits with microstrip lines using open or shorted stubs for matching or realization of filters, the actual circuit can be substantially mismatched when the length of the open stub is below 30 ...
  • Realization of Nth-Order Voltage Transfer Function using Current Conveyors CCII 

    Cajka, J.; Dostal, T.; Vrba, K. (Společnost pro radioelektronické inženýrství, 1997-06)
    A universal method for the realization of arbitrary voltage transfer function in canonic form is presented. A voltage-controlled current-source using a plus-type second-generation current conveyor is here applied as the ...
