A systematic, automatable, unified methodology is presented for the modeling of non-linear large-signal dynamics and eigenvalue analysis of microgrid systems. Unlike nodal-based simulators and typical state-variable methods that require Kirchhoff’s current law analysis, a state-space model is systematically derived from the netlist of the equivalent qd microgrid circuit model. The model may be ...

The aim of this paper is to analyse continuity properties of mutual and conditional entropies, between the input and output of a channel with additive noise. Our attention is focused mainly on a distinctly non-Gaussian situation, for both large and small signal-to-noise ratio. To our knowledge, this nontrivial aspect has not been discussed before at the level of generality adopted in this paper...

The purpose of this part of the notes is to briefly review some of the prerequisite course materials related to characteristics of active device in microelectronic circuits. We summarize dc, large-signal and small-signal (incremental) models of two major types of active devices used in analog, digital and mixed-mode integrated circuits: metal-oxide-semiconductor field-effect transistors (MOSFET...

A nonlinear detector simulation technique that can be used together with the discrete technique for a rapid radio receiver electromagnetic compatibility and electromagnetic interference (EMC/EMI) simulation up to the baseband signal processing path at the system level is proposed. The technique presented allows one to simulate an amplitude modulation (AM) detector in the large signal mode as we...

one of the most common signals used for achieving high range resolution in radar is stepped-frequency signals. when a target is stationary in these radars, dft (discrete fourier transform) based processing is used to attain high range resolution profile (hrrp). however, in the case of moving target, due to spreading of the echo signal spectrum, dft based processing is not optimal and decreases ...

A test point selection algorithm TEPSAUS (TEst-Point Selection Algorithm Using Small signal model) for scan based build-in self-test (BIST) is proposed in this paper. In order to reduce the computational complexity, the algorithm uses Small Signal Model (SSM) to build recursion formulas for cost reduction functions. With the recursion functions, the cost reduction functions can be calculated ef...

This paper presents a technique to evaluate the timing variation of SRAM. Specifically, a method called loop flattening that reduces the evaluation of the timing statistics in the complex, highly structured circuit to that of a single chain of component circuits is justified. To then very quickly evaluate the timing delay of a single chain, a statistical method based on Importance Sampling augm...

This paper modeled a doubly fed induction generator (DFIG) based offshore wind farm integrated through a voltage source converter –based high voltage direct current (VSC-HVDC) transmission system, which is collected with infinite bus for small signal stability analysis. The control system of HVDC system is considered for the stability analysis. The impact of the VSC control parameters on the ne...

This paper provides an analysis of a log detector in order to determine its response to a multi-tone input for detection of spurious emissions in a radio frequency transmitter. Treatment is given to the single tone response of the log detector and extended to a two-tone log detector system, where a large signal and a small signal are present. The large signal is observed to experience logarithm...

Power systems are subjected to small–signal oscillations that can be caused by sudden change in the value of large loads. To avoid the dangers of these oscillations, the Power System Stabilizers (PSSs) are used. When the PSSs can not be effective enough, installation of the Thyristor–based compensators to increase the oscillations damping is a suitable method. In this paper, a Static Synchronou...
