AN ADVANCED ANALYSIS METHOD OF COLPITTS OSCILLATOR CIRCUIT

Abstract

Oscillator circuits are one of the most important components in communication devices. Although oscillator circuits have been widely used in practice, their analytical theories still have more errors when calculating the design of oscillator circuits in the high-frequency region. In this paper, we review current theoretical analysis methods of the Colpitts oscillator circuit and point out the limitations of these methods. From there, we propose an advanced analysis method to increase the accuracy of calculating the oscillation frequency in the high-frequency domain.
