Title
Realization Approach for Sinusoidal Signal Generation and Circuit with Easy Control
Abstract
A new approach for realizing sinusoidal signal with quadrature property is proposed, which employs simple analog building blocks and facilitates easy tuning of the oscillation frequency, through a gain factor. The proposed approach is used for realizing a novel quadrature oscillator circuit, which requires three current feedback operational amplifiers and passive components. The proposed circuit provides outputs at low impedance terminals, and benefits from easy control over the frequency of oscillation (FO), which depends on resistive ratio, rather than absolute resistor values. The frequency control is also independent of the condition of oscillation (CO). The nonideal effects and the parasitic studies are presented. The verification of the proposed realization scheme for quadrature oscillators and the new circuit is carried out through both simulation studies and experimental results, using the commercially available chips.
