An Introduction to Modeling Embedded Mixed-Signal Systems

Modeling and Simulation of Substrate Noise in Mixed-Signal Circuits Applied to a Special VCO

The mixed-signal circuits with both analog and digital blocks on a single chip have wide applications in communication and RF circuits. Integrating these two blocks can cause serious problems especially in applications requiring fast digital circuits and high performance analog blocks. Fast switching in digital blocks generates a noise which can be introduced to analog circuits by the common su...

An Efficient Technique for Substrate Coupling Parasitic Extraction with Application to RF/Microwave Spiral Inductors (RESEARCH NOTE)

This paper presents an efficient modeling method, based on the microstrip lines theory, for the coupling between a sub­strate backplane and a device contact. We derive simple closed-form formulas for rapid extraction of substrate parasitics. We use these formulas to model spiral inductors as important substrate-noise sources in mixed-signal systems. The proposed model is verified for the freque...

Proceedings of the 5th Progress Symposium on Embedded Systems

The formal language is the formalization of SystemC. The language semantics of was formally defined in a standard structured operational semantics (SOS) style. In this paper, we first provide an overview of the current status of the formal language and show some practical applications of . Then, we give an outline for the latest developments of . These developments include extensions of ! for m...

Estimation of harmonic interference parameters of surface-NMR signal using an adaptive method and residual signal power

Surface nuclear magnetic resonance (surface-NMR) method is a well-known tool for determining the water-bearing layers and subsurface resistivity structure. Harmonic interference is an inevitable interference in surface-NMR measurements. Accurate estimation of harmonic interference parameters (i.e., fundamental frequency, phase and amplitude) leads to better retrieval of power-line harmonics and...
