The article has dealt with problems of noise measurement located on the receiver side. The influence of noise bandwidth B and receiver gain GREC on the measured power level FNwas discussed. The digital realization of B enables a revival of the signal generator method. The need for a calibrated noise generator is eliminated and a VNA can be used a receiver. A transistor measurement shows that the linearity...
This paper reviews some recent achievements regarding behavior and modeling of low-frequency noise sources that have the potential to improve phase noise simulations significantly. This paper discusses a heuristic interpretation of how time-varying currents affect low-frequency noise sources, review physics-based device simulations, and then present how the sources can be implemented in commercial...
