Abstract:SUMMARYThe first step of this work is to study the susceptibility of a radiofrequency oscillator to deterministic disturbance sources.A Colpitts oscillator, working around a 4 GHz frequency, contains a heterojunction bipolar transistor with a silicon-germanium base as an active device. A mixed-mode analysis is involved, applying a microscopic drift diffusion model to the device, whereas the rest of the circuit used is governed by Kirchhoff's laws.We assume that this tool is very relevant to grasp the influence… Show more
