  • Current-Mode CCII+ Based Oscillator Circuits using a Conventional and a Modified Wien-Bridge with All Capacitors Grounded 

    Bajer, J.; Lahiri, A.; Biolek, Dalibor (Společnost pro radioelektronické inženýrství, 2011-04)
    The paper deals with a pair of current-mode sine-wave oscillator circuits. Both these circuits are implemented using positive second-generation current conveyors (CCII+). The principle of the first oscillator is based on ...
  • Four-Phase Oscillators Employing Two Active Elements 

    Biolková, Viera; Bajer, J.; Biolek, Dalibor (Společnost pro radioelektronické inženýrství, 2011-04)
    Two novel four-phase voltage-output oscillators are proposed. These circuits can also be utilized as quadrature oscillators with floating outputs. Each oscillator employs two DO-CIBA (Differential Output- Current Inverter ...
  • High Input Impedance Voltage-Mode Biquad Filter Using VD-DIBAs 

    Jaikla, W.; Biolek, Dalibor; Siripongdee, S.; Bajer, J. (Společnost pro radioelektronické inženýrství, 2014-09)
    This paper deals with a single-input multiple-output biquadratic filter providing three functions (low-pass, high-pass and band-pass) based on voltage differencing differential input buffered amplifier (VD-DIBA). The quality ...
  • A Simple Current-Mode Quadrature Oscillator Using Single CDTA 

    Jaikla, W.; Siripruchyanun, M.; Bajer, J.; Biolek, Dalibor (Společnost pro radioelektronické inženýrství, 2008-12)
    This article presents a simple current-mode quadrature oscillator using a single Current Differencing Transconductance Amplifier (CDTA) as the active element. The oscillation condition and oscillation frequency can be ...
