dc.description.abstractNew Current Differencing Buffered Amplifier (CDBA) - based multifilter function topologies are presented. Electronic tuning is derived by appropriate insertion of a multiplier element whose control voltage (Vc) tunes the select frequency in a range of 200KHz ≤ fo ≤ 1MHz. The circuits also realize a voltage controlled quadrature oscillator (VCQO) with suitable design. Analysis on the effects of the CDBA-parasitic components indicates low active-sensitivity and good frequency-stability of the oscillator. The multifunction performance has been verified both with PSPICE macromodel simulation and by hardware circuit tests. A novel method of measuring the oscillator frequency-tuning error (Δf) based on the Nyquist plot is presented that shows Δ f ≈ 2%en_US
