A METHOD OF ACCURATELY COMPUTING AMPLITUDE AND PHASE NOISE OF OSCILLATORS AND GENERATING A GENERAL PURPOSE NOISE MODEL OF OSCILLATORS, MIXERS, AND AMPLIFIERS IN FREQUENCY DOMAIN ANALYSIS OF ANALOG ELECTRONIC CIRCUITS AND USING SAME

Publication number: 20080048675

Abstract: A method of accurately computing amplitude and phase noise of oscillators and generating a general purpose noise model of oscillators, mixers, and amplifiers in frequency domain analysis of analog electronic circuits and using same. A method for computing amplitude jitter, frequency jitter, sideband noise, and plain phase noise for oscillators, mixers, and amplifiers and modeling these sub-circuits accurately within a frequency domain analysis of an analog electronic circuit.

SOLVING THE PERIODIC STEADY-STATE OPERATING CONDITION OF A PHASE-LOCKED LOOP OR DELAY-LOCKED LOOP CIRCUIT USING A TRANSIENT ESTIMATION METHOD

Publication number: 20070255547

Abstract: A system and method for quickly determining the steady-state condition of a phase-locked loop or a delay-locked loop circuit by simulating a phase-locked loop in DC transient and periodic steady-state analysis and controlling phase and/or delay of the voltage-controlled oscillator and/or reference source, signal, or oscillator.
