Structured Design of Integrated Subscriber Line Interface System and Circuit

Abstract

A structured design of Subscriber Line Interface System and Circuit will be described. A high level synthesis allows extracting overall system and circuit requirements to satisfy the desired specifications, standards, and a robust implementation. For this purpose, first the output driving stage will be analyzed and then, dc, ac, and longitudinal balance feedbacks will be considered. Then based on extracted system specifications, optimum circuit design of line-driver will be described. High-level design of line-driver as the most important circuit block which is optimized for stability, accuracy, area, and power dissipation will be elaborated.

Part I: Mixed-Signal Performance of Various High-Voltage Drain-Extended MOS Devices

“…For high-speed data transfer on a twisted-pair copper connection, a subscriber line interface circuit integrated in CMOS technology is required [12]- [14]. Power management modules such as the high-efficiency switch-mode dc-dc converter are critical building blocks for state-of-the-art portable applications.…”
