  • ARC Filters Using Only Followers 

    Dostal, T. (Společnost pro radioelektronické inženýrství, 1999-04)
    Several structures of the active RC filters using non-inverting voltage unity-gain followers and dual current positive followers are given in this paper. These structures can be suitable implemented by the positive second ...
  • Biquads Based on Single Negative Impedance Converter Implemented by Classical Current Conveyor 

    Dostal, T.; Axman, V. (Společnost pro radioelektronické inženýrství, 2007-09)
    The paper deals with continuous-time ARC biquadratic (second-order) filters based on the single classical three-port current conveyors, so called second generation CC II. A unique application of the CC II is discussed, ...
  • Current-Mode Circuits Based on SIMO OTA: Review and New Applications in Filters 

    Dostál, Tomáš; Šotner, Roman; Slezák, Josef (Hikari, 2009-11-06)
    The paper deals with design of low-order RC filters working in current mode (CM). As the basic building blocks, transconductors (OTA) with single input and multiple outputs are used. One-loop, two-loop and multi-loop ...
  • High Frequency State-Variable Biquadratic Active Filters 

    Dostal, T. (Společnost pro radioelektronické inženýrství, 1998-04)
    The state-variable (KHN) active RC biquadratic filters with good performance in high frequency range , flexibility of outputs (LP, HP, BP), low sensitivities in novel current and hybrid modes, using current conveyors, ...
  • On Canonical Structures of ARC Biquadratic Filters with Single Transconductor 

    Dostal, T. (Společnost pro radioelektronické inženýrství, 2006-06)
    The paper deals with simple canonical structures of the second order ARC filters employing only single transconductor (OTA) and passive components R and C. A systematic design procedure of this circuits based on the given ...
