Noise in a phase-quadrature pulsed energy restore oscillator

Low phase noise oscillators are ubiquitous building blocks for radio frequency applications and pulse energy restore oscillator can represent the paradigm for a circuit class characterized by improved noise figures. Design of these oscillators requires numerical simulation tools capable of finding both a steady state solution and an accurate variational representation of the circuit model, even if the circuit model does not satisfy Lipschitz continuity. An extended steady state method with this capability has been implemented in our simulator and it has been used to asses the design choices in a test case oscillator, as described in this paper.
