In this work, a quantum fluctuation operator (QFO) has been formulated to achieve realistic flicker noise simulations which are currently not available on BSIM platforms. The responsibility of the operator is to create a closer representation of flicker noise in deep n-well (DNW) MOSFETs based on probabilistic densities. It is well known that flicker (or 1/f ) noise is generated by a combinatio...

In this work we review the processes of phase noise and jitter in electronic oscillators and the relationship between the two. Frequency and time domain simulation techniques and results are presented through the study of performance enhancement for a CMOS LC oscillator. The studied enhancements significantly reduce flicker noise upconversion, while the results demonstrate good agreement betwee...

As a consequence of a general trend in the physics of oscillators and clocks towards optics, phase and frequency metrology is rapidly moving to optics too. Yet, optics is not replacing the traditional radio-frequency (RF) and microwave domains. Instead, it adds tough challenges. Precision frequency-stability measurements are chiefly based on the measurement of phase noise, which is the main foc...

PLLs are important building blocks that are used to generate and distribute clocks in all high-performance digital systems. Integrating PLLs on large digital chips in deep submicron processes poses three main challenges. First, power supply noise caused by increased digital switching currents degrades the jitter performance of the VCO. Second, the wide loop bandwidth required to suppress ring o...

2014 It is shown that assuming weak inversion, low drain current asymptotic value of the gate equivalent noise resistor is given by n2/2 UT/ID, corresponding to shot noise. Measurements confirming this theory as well as flicker noise measurements on n and p channel transistors integrated with either bulk or SOS CMOS silicon gate technology are presented.

The measurement of the close-to-the-carrier noise of two-port radio frequency and microwave devices is a relevant issue in time and frequency metrology and in some fields of electronics, physics, and optics. While phase noise is the main concern, amplitude noise is often of interest. Presently the highest sensitivity is achieved with the interferometric method, that consists of the amplificatio...

An internal shock model is proposed to interpret the radio to infrared (IR) emission of the compact jets observed in the hard spectral state of X-ray binaries. Assuming that the specific bulk Lorentz factor of the jet at its base varies with a flicker noise power spectrum [i.e. P(f) ∝ 1/f], we estimate the energy dissipation profile along the jet and the resulting partially self-absorbed synchr...
