The designer needs simple and accurate models to estimate noise in MOS transistors as a function of their size, bias point and technology. In this work, we present a simple, continuous, physics-based model for flicker noise. We review also thermal noise and we examine the behavior of the corner frequency (fc) in terms of the bias point. The expressions that are presented are simple and valid in...

Abstrac t In this work we analyse the applicability of low-frequency (LF) noise measurement in order to study the defectiveness in the gate oxide of power MOSFETs. To this purpose we implement a low-noise experimental set-up, which is able to measure the drain current flicker (“1/f”) noise of the device under test (DUT). First, we show how these measurements can be used to empirically detect th...

Using Precise Point Positioning (PPP) we show the potential for comparing frequency standards with time stabilities of under 300 ps in flicker phase noise for time periods of 1 to 10 d. This leads to comparisons at 1 part in 10 or better at 10 d. We compare short baseline PPP results with 2 hour data from the NIST Measurements System. We compare results from the NIST – USNO baseline with hourly...

Charge transport properties of metal-molecule interfaces depend strongly on the character of molecule-electrode interactions. Although through-bond coupled systems have attracted the most attention, through-space coupling is important in molecular systems when, for example, through-bond coupling is suppressed due to quantum interference effects. To date, a probe that clearly distinguishes these...

In this paper, a 1.2-V RF front-end realized for the personal communications services (PCS) direct conversion receiver is presented. The RF front-end comprises a low-noise amplifier (LNA), quadrature mixers, and active RC low-pass filters with gain control. Quadrature local oscillator (LO) signals are generated on chip by a double-frequency voltage-controlled oscillator (VCO) and frequency divi...

Using the method developed in a recent paper (Euro. Phys. J. B 92.8 (2019): 1-28) we consider $1/f$ noise two-dimensional electron gas (2DEG). The coherence length of system is considered as basic parameter for discretizing space, inside which dynamics electrons described by quantum mechanics, while scales much larger than it semi-classical. For our model, based on Thomas-Fermi-Dirac approximat...
