CFOA-Based Sinusoidal Oscillator with Complete Resistive Tuning and Low Parametric Sensitivity

Abstract

In this paper, a second-order sinusoidal oscillator (SO) has been presented using current-feedback operational amplifiers (CFOAs) as the active element. The proposed oscillator uses five resistors and two grounded capacitors in its circuit design, making it simple and cost-effective to implement. Its design allows for greater control and flexibility in designing the oscillator circuit, making it an attractive option for a variety of applications. It also provides independent resistive tuning, allowing for greater control and flexibility in designing the oscillator circuit. Additionally, it offers low parameter sensitivity, makes it more stable and reliable. These features make it a valuable tool for engineers and designers in a variety of applications, including signal processing, communication systems, and control systems. The frequency tuning expression achieved has the ability to tune frequencies in a broad range of frequencies. PSPICE tool is used to simulate and analyze the behavior of the proposed circuit. The total harmonic distortion recorded was 5[Formula: see text].
