MULTICRITERIA VCO DESIGN

摘要

High frequency, voltage-controlled oscillators (VCO) are important components of modern RF systems. They are characterized by a set of parameters, which must be analyzed and optimized (for example, phase noise, frequency tuning range, tuning linearity and output power). Many studies are dedicated to the research of VCO characteristics. Nevertheless, due to the increasing requirements of VCOs for modern electronic systems, this subject does not lose its significance. One of the important stages of VCO development is the analysis of circuit stability and conditions of oscillation development. In this article, a method of oscillator circuit analysis based on the Nyquist criterium is offered.
