Substrate Crosstalk Analysis in Mixed Signal CMOS Integrated Circuits

| Substrate crosstalk modeling and analysis techniques for a reliable SoC oriented mixed signal IC design are outlined. Substrate noise measurements by use of a source follower and a latched comparator clearly indicate that L di=dt and R i e ects on Vdd/Gnd wirings appear in the substrate. An experimental full chip substrate crosstalk veri cation system based on a macroscopic substrate noise mo...

Efficient and Accurate Modeling and Simulation Techniques for Substrate Coupling Analysis in Deep Submicron Mixed-Signal IC’s

Phase-locked loops (PLLs) are used in wireless receivers to implement a variety of functions, such as frequency synthesis, clock recovery, demodulation, and mixed-signal integrated circuits. Substrate coupling noise is a key problem in today’s large mixed-signal systems. Switching-noise generated by digital circuits can be coupled to sensitive analog circuits through the substrate, can degrade ...

Behavioral modeling of continuous time ∆Σ modulators

A mixed-signal continuous time behavioral model of a continuous time delta-sigma modulator (CT ∆Σ) is presented. CT ∆Σ modulators, by their nature, are mixed-signal systems. That fact creates a discontinuity in the traditional IC design flow which assumes that “discrete” and “continuous” time domain designs require separate design tools. In this work, we present a top level behavioral CT ∆Σ mod...

Crosstalk effects in mixed-signal ICs in deep submicron digital CMOS technology

This paper illustrates the crosstalk phenomenon and its impact on the design of mixed analog/digital circuits with high accuracy specifications. Generation of digital disturbs, propagation through the substrate, and effects on analog devices are considered, with particular emphasis on integrated circuits realized on heavily doped substrate, where traditional shielding is less effective.
