• Substrate_coupling abstract "In an integrated circuit, a signal can couple from one node to another via the substrate. This phenomenon is referred to as substrate coupling or substrate noise coupling.The push for reduced cost, more compact circuit boards, and added customer features has providedincentives for the inclusion of analog functions on primarily digital MOS integrated circuits (ICs) formingmixed-signal ICs. In these systems, the speed of digital circuits is constantly increasing, chips arebecoming more densely packed, interconnect layers are added, and analog resolution is increased. In addition, recent increase in wireless applications and its growing market are introducing a new set of aggressive design goals for realizing mixed-signal systems. Here, the designer integrates radio frequency(RF) analog and base band digital circuitry on a single chip. The goal is to make single-chip radio frequencyintegrated circuits (RFICs) on silicon, where all the blocks are fabricated on the same chip. One of the advantages of this integration is low power dissipation for portability due to a reduction in the number of package pins and associated bond wire capacitance. Another reason that an integrated solution offers lower power consumption is that routing high-frequency signals off-chip often requires a 50Ω impedance match, which can result in higher power dissipation. Other advantages include improved high-frequency performance due to reduced package interconnect parasitics, higher system reliability, smaller package count, and higher integration of RF components with VLSI-compatible digital circuits. In fact, the single-chip transceiver is now a reality.The design of such systems, however, is a complicated task. There are two main challenges in realizingmixed-signal ICs. The first challenging task, specific to RFICs, is to fabricate good on-chip passive elementssuch as high-Q inductors. The second challenging task, applicable to any mixed-signal IC and the subjectof this chapter, is to minimize noise coupling between various parts of the system to avoid any malfunctioningof the system. In other words, for successful system-on-chip integration of mixed-signal systems, thenoise coupling caused by nonideal isolation must be minimized so that sensitive analog circuits and noisy digital circuits can effectively coexist, and the system operates correctly. To elaborate, note that in mixed-signalcircuits, both sensitive analog circuits and high-swing high-frequency noise injector digital circuits may bepresent on the same chip, leading to undesired signal coupling between these two types of circuit via the conductive substrate. The reduced distance between these circuits, which is the result of constant technology scaling (see Moore's law and the International Technology Roadmap for Semiconductors),exacerbates the coupling. The problem is severe, since signals of different nature and strength interfere,thus affecting the overall performance, which demands higher clock rates and greater analogprecisions.The primary mixed-signal noise coupling problem comes from fast-changing digital signals coupling to sensitive analog nodes. Another significant cause of undesired signalcoupling is the Crosstalk (electronics) between analog nodes themselves owing to high-frequency/high-power analogsignals. One of the media through which mixed-signal noise coupling occurs is the substrate. Digital operations cause fluctuations in the underlying substrate voltage, which spreads through the common substrate causing variations in the substrate potential of sensitive devices in the analog section. Similarly, in the case of crosstalk between analog nodes, a signal can couple from one node to another via the substrate.This phenomenon is referred to as substrate coupling or substrate noise coupling.".
