  • All-Pass Filters in Current Mode 

    Dostal, T. (Společnost pro radioelektronické inženýrství, 2005-09)
    Analogue first, second and high-order all-pass active filters in the current mode, with constant group delay and magnitude responses, are presented in this paper. These filters are based on a modification of the multi-loop ...
  • 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 ...
  • Filters with Multi-Loop Feedback Structure in Current Mode 

    Dostal, T. (Společnost pro radioelektronické inženýrství, 2003-09)
    Universal multifunctional (low-pass, high-pass, band-pass, band-reject and all-pass) nth-order active RC filters in current mode are presented in this paper. The filters are based on several multi-loop feedback and ...
  • High-Order Lowpass Filters Using DVCC Elements 

    Cajka, J.; Dostal, T.; Vrba, K. (Společnost pro radioelektronické inženýrství, 2002-06)
    Special cells using a differential voltage current conveyor are presented. The use of these cells for high-order lowpass filter design is described. The filters can be designed to operate in different modes.
  • Nodal Analysis of Circuits Containing Current Conveyors 

    Rybin, A. I.; Dostal, T. (Společnost pro radioelektronické inženýrství, 2001-09)
    A special method of the nodal analysis of the circuits containing several types of the multiport current conveyors is presented in this paper. The method is based on the given regular and homogeneous models of the irregular ...
  • 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 ...
  • Přímá realizace přenosové funkce obvody s moderními funkčními bloky 

    Vyskočil, Jiří
    Tématem mé bakalářské práce je přímá realizace přenosové funkce obvody s moderními funkčními bloky. Jedná se o návrh multifunkčních kmitočtových filtrů. Výhodou přímé realizace přenosové funkce je např. snadná modifikace ...
