oscillator, working around a 3 GHz frequency, contains a double gate Metal
Oxide Semiconductor transistor (DGMOS). A mixed-mode analysis is involved,
applying a quantum model to the device, whereas the rest of the considered
circuit is governed by Kirchhoff’s laws. The Linear Time Variant (LTV) model of
phase noise is based on the Impulse Sensitivity Function of the Colpitts
Oscillator which describes carefully the sensitivity of an oscillator to any
impulse current injection in any node of the circuit. Finally, we improve the
phase noise modeling, confronting some analytical developments to mixed-mode
