Filters with Multi-Loop Feedback Structure in Current Mode
(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 ...
On Canonical Structures of ARC Biquadratic Filters with Single Transconductor
(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 ...
Modeling of Modern Active Devices for Simulations of Analog Circuits in PSpice
(Společnost pro radioelektronické inženýrství, 2000-09)

Adjoint Networks with Inverting and Noninverting Current Conveyors
(Společnost pro radioelektronické inženýrství, 2000-04)
Four types of second-generation current conveyors are shown. The realisation of the above conveyors using differential voltage current conveyors (VDCC) is presented. Two examples illustrate the building of adjoint networks ...
ARC Filters Using Only Followers
(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 ...
Signal-Flow Graph Network Analysis
(Společnost pro radioelektronické inženýrství, 1992-10)
A novel type of signal-flow graph is presented creating minimum number of nodes for independent voltages only. The graph will be derived by inspection of the network using special transforming T-graphs. The method is useful ...
