“…The design of electronic circuit in analog signal processing has been emphasized in the use of active building block [6][7][8]. Particularly, the electronically tunable active building blocks have attracted significant research attention since analog circuits using electronically tunable active building block give more fine-tuning than adjusting the value of passive device.…”

A new configuration of voltage-mode quadrature sinusoidal oscillator is proposed. The proposed oscillator employs two voltage differencing current conveyors (VDCCs), two resistors, and two grounded capacitors. In this design, the use of multiple/dual output terminal active building block is not required. The tuning of frequency of oscillation (FO) can be done electronically by adjusting the bias current of active device without affecting condition of oscillation (CO). The electronic tuning can be done by controlling the bias current using a digital circuit. The amplitude of two sinusoidal outputs is equal when the frequency of oscillation is tuned. This makes the sinusoidal output voltages meet good total harmonic distortions (THD). Moreover, the proposed circuit can provide the sinusoidal output current with high impedance which is connected to external load or to another circuit without the use of buffer device. To confirm that the oscillator can generate the quadrature sinusoidal output signal, the experimental results using VDCC constructed from commercially available ICs are also included. The experimental results agree well with theoretical anticipation.

Recently this author published a paper 1 discussing the transformation of grounded inductors to°o ating inductors using operational°oating ampli¯er (OFA) or°oating current conveyor (FCCII). The author classi¯ed the paper as a partially review paper as stated in the abstract and in the introduction of Ref. 1 The author states in the abstract that: It is well known that a°o ating inductor circuit is realized from a grounded inductor circuit by replacing the operational ampli¯er by a°oating operational transconductance ampli¯er. This idea is extended to transform current conveyor grounded inductors to°oating inductors by replacing the current conveyor by the recently introduced°oating current conveyor.
