Simulation of substrate coupling in mixed-signal IC's using an efficient and real-time macromodel

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...

Measuring mixed-signal substrate coupling

A measurement method is proposed to characterize the substrate coupling between digital and analog sections of a mixed-signal CMOS chip. Induced noise and spurious signals can be measured by a custom-designed analog sensor. This paper proposes a method that, when given such a sensor, allows to measure the crosstalk between digital and analog chip sections. Calibrated sampling scope measurements...

Evaluating Noise Coupling Issues in Mixed-Signal 3D ICs

Technology for 3D ICs is slowly becoming mainsteam such that integrating complete mixed digital-analog-RF systems is not only possible but almost unavoidable. Because of the close proximity of the different substrates switching noise from digital circuits are easily coupled through to severely degrade the performance of sensitive analog/RF circuits, as illustrated in Fig 1. In this paper, we ev...
