  • 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 ...
  • ARC Filters with Diamond Transistors and Buffers 

    Dostal, T. (Společnost pro radioelektronické inženýrství, 1998-12)
    Active RC first and second order filters using diamond transistors (voltage controlled current sources) and voltage diamond buffers (voltage controlled voltage sources) are given in this paper. Circuits are simulated and ...
  • A CMOS Multiplied Input Differential Difference Amplifier: A New Active Device and Its Applications 

    Šotner, Roman; Jeřábek, Jan; Prokop, Roman; Kledrowetz, Vilém; Polák, Josef (MDPI AG, 2017-01-26)
    This paper presents a newly developed active device, referred to as a multiplied input differential difference amplifier (MIDDA), which allows operations of summation/subtraction and multiplication of input signals. It was ...
  • 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, ...
  • New voltage-mode universal filter and sinusoidal oscillator using only single DBTA 

    Herencsár, Norbert; Koton, Jaroslav; Vrba, Kamil; Lattenberg, Ivo (Taylor & Francis, 2010-04-01)
    In this article, a new voltage-mode second-order universal frequency filter and sinusoidal oscillator using only single differential-input buffered and transconductance amplifier (DBTA) is presented. The proposed voltage-mode ...
