Webinar: Advanced Analog Design Using S-parameters

August 22, 2023 @ 8:00 AM - 9:00 AM

Advanced Analog Design using S Parameters

When: Tuesday, Aug 22, 2023 at 8:00 am (PDT)

Duration: 60 Minutes

This webinar highlights the importance of S-parameters to IC design and how Semtech Corporation, a high-performance semiconductor, IoT systems and Cloud connectivity service provider, utilizes Siemens AFS XT simulation technology to accelerate Semtech’s design process without compromising on accuracy to develop differentiated analog solutions for wired and wireless applications. Two case studies of analog circuits will be discussed.

Advanced Analog Design using S-Parameters


IC design is transforming at an accelerated pace along with fabrication technology. The need to incorporate more functionality has led to denser dies, multi-die chips, stacked 3D ICs and advanced packaging. Design technology continues to progress toward supporting higher data rates to address the increasing demand for more and enhanced connectivity. We now must deal with much more power, ground and clock signals and their distribution on die, between dies, on package and on board. Signal transmission and reflection needs to be well understood to properly design for signal integrity in various signal conduits. S-parameters (scattering parameters) play a crucial part in IC design in representing passive structures and interconnects with frequency variable behavior in the RF realm. Accurate verification with these components amid large designs and sub-systems is key for first time right tapeouts, along with a fast verification methodology that accelerates development.

Semtech provides unique differentiation with its wired and wireless IC technology for infrastructure, industrial, automotive and consumer electronics applications. Semtech’s Signal Integrity Products (SIP) Group provides high performance TIAs, CDRs, linear equalizers and laser drivers for optical module solutions used by leading companies in hyperscale data center applications, enterprise networking, wireless infrastructure, including 5G fronthaul and midhaul, and passive optical networking/fiber-to-the-home using CMOS and BiCMOS process technologies.

In this webinar, we focus on Semtech’s requirements of S-parameters for analog circuit development and how Siemens Analog FastSPICE (AFS) eXTreme technology provides differentiated performance across DC, AC, transient, transient noise and RF analyses. Two case studies on 26GBd Analog Delay Line and 25Gb/s Receiver will be showcased.
