Original Abstract
We introduced features of adjustable current feedback amplifier modification as a basis of oscillators in this paper. Key feature of presented active element is a current gain and intrinsic resistance control. Quadrature oscillator with this block is presented. Direct electronic control of important features (oscillation frequency and oscillation condition) is discussed. An example of intended suggestions was verified by PSpice simulations with designed model of active element.
Keywords
Current feedback amplifier, direct electronic control, current gain, controllable quadrature oscillators.
