Single-resistance-controlled sinusoidal oscillators employing single FTFN and grounded capacitors

In this study new single-resistance controlled sinusoidal oscillator topologies are proposed. All of the proposed oscillators use single FTFN, two grounded capacitors which is suitable for IC implementation, and five resistors. They have passive sensitivities less than unity. The oscillators provide non-interactive control of oscillation condition and oscillation frequency and they can easily be converted to voltage-controlled oscillators. Theoretical analyses are verified with PSPICE simulations.
