“…The symbol and implementation details of FTFNs are shown in Figs. 1 and 2 and are reported in [28][29][30]. For experimental purpose the FTFNs were constructed using commercially available current feedback op-amp IC AD844s and in PSPICE macromodals of AD844 supported by Analog Devices Inc. were used [30].…”

“…They find numerous applications in instrumentation, measurement, control and communication systems. New oscillator OPEN ACCESS circuits based on various active elements have been proposed continuously [1][2][3][4]. Most oscillators proposed in the literature have been on an ad hoc basis, i.e., a topology is chosen using an arbitrary procedure and is then analyzed.…”

Derivation of Oscillators from Biquadratic Band Pass Filters Using Circuit Transformations

Network transformations are the techniques to obtain new functional schemes from available circuits. They are systematic methodologies, since each transformation technique can be applied to many circuits to obtain the desired functions or characteristics. A convenient network transformation method, exploiting different circuit transformations, for deriving linear sinusoidal oscillators from biquadratic band pass filters is proposed. This method with generality can be applied to any band pass filter. The oscillation frequency of the new obtained oscillator is identical to the center frequency of the original band pass filter, and the useful properties of the selected band pass filter can be retained. Two examples are illustrated to confirm the feasibility of the proposed approach. The workability of the obtained oscillators is verified with PSPICE simulations.

“…A minimum of one active element is needed to implement the inductor. SRCOs designed using a single opamp in [1] requires minimum seven passive components, while single current conveyor or FTFN based oscillators in [2] and [4] require five passive components only. Another important topological feature desired was use of grounded capacitors.…”

Two oscillator topologies each employing a single differential voltage complementary current conveyor (DVCCC) are presented. The first oscillator uses a single active element, five passive components, grounded capacitors, has independent control of frequency and condition of oscillation. It has a current mode output and can be extended to provide a voltage mode output. It combines all the features of the current state-of-art oscillators. The second oscillator uses a single DVCCC, four passive elements, grounded capacitors and provides independent control of frequency. This oscillator not only has all the desired oscillator features, but requires lesser passive components. Theoretical analysis of these oscillators was verified with SPICE simulations.
