  • Abstract
    A tunable active-phase-compensated universal biquadratic filter is presented. It is shown that for the matched amplifiers the circuit not only exhibits stable Q-factor but also tracks the pole-zero frequencies. The proposed circuit provides simultaneously four basic biquadratic realisations¿notch, lowpass, highpass and bandpass.
