The Evaluation of Phase Noise in Low Noise Oscillators

1987 IEEE MTT-S International Microwave Symposium Digest, 1987
A new measurement system for the characterisation of low noise oscillators is described. Injection locking rather than phase locking is used to achieve phase quadrature in the two oscillator phase detector method. This method is simpler to implement than conventional phase locked systems and by using a fixed rather than an electronically tuned ...

Noise-induced phase synchronization enhanced by dichotomic noise

Physical Review E, 2001
We study the nonlinear response of a stochastic bistable system driven by both a weak periodic signal and a dichotomic noise in terms of stochastic phase synchronization. We show that the effect of noise-induced phase synchronization can be significantly enhanced by the addition of a dichotomic noise.

A new method for phase noise measurement

IMTC/2002. Proceedings of the 19th IEEE Instrumentation and Measurement Technology Conference (IEEE Cat. No.00CH37276), 2003
The paper describes a new method for phase noise measurement and a virtual instrument capable of investigating the phase noise spectral contents of sinusoidal carriers in a wide range of frequencies offset with variable frequency resolution. The proposed method harmonizes two complementary digital signal processing approaches already proposed by the ...

Method for simulating phase noise in oscillators

IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 2001
Summary: A method for simulating phase noise in autonomous circuits is described. It employs the sensitivity functions of the oscillation period with respect to state functions and is based on an extension of the conventional harmonic-balance method to multitone analysis.

Correlation Between Microwave Transistors Low Frequency Noise, Amplifiers Residual Phase Noise and Oscillators Phase Noise Consequences On Oscillator Phase Noise Modeling

1997
The conversion of low frequency noise into phase noise in a high frequency oscillator depends strongly on the active device type and operating conditions. Experimental setups are presented to achieve the best choice of a transistor to be used in low noise oscillators and to study the correlation between phase noise and low frequency noise.
