Injection pulling by interference signals is an undesired phenomenon in front-end oscillators, which causes a shift of the oscillation frequency and degrades the output spectrum. This paper presents a semi-analytical formulation for the insightful analysis of injection-pulling phenomena in the presence of a modulated carrier or chirp signal. The formulation enables an efficient analysis of interference...
In this work, different techniques are proposed for the computer aided design of voltage-controlled oscillators (VCO). The first technique allows setting the operation frequency band for specific values of the tuning voltage. The second technique imposes a linear frequency-voltage characteristic with the aid of an auxiliary generator. To follow this characteristic, the circuit is solved in terms of...
