Thermal and Stress Analysis of 3D-ICs with Celsius Thermal Solver

3D-ICs integrate many dies that are densely packed, which leads to heat generation that causes performance issues. This white paper helps designers understand the cross-fabric thermal challenges introduced by 3D-ICs and explains how the Cadence® Celsius™ Thermal Solver helps designers analyze and develop strategies to mitigate this impact.

Reduce SWaP, Increase Performance of Phased Arrays with an Innovative Filtering Approach

The spectral environment is quickly changing today. It’s becoming more crowded, which is resulting in an increase in spectral noise. This is presenting a variety of new challenges for RF designers, both in terms of the architecture and power needed to transmit and receive signals and the types of jobs filters need to perform in receivers (Rx) and transmitters (Tx).

Can deterministic digital phased array control be delivered over fiber?

Reporting progress at Teledyne e2v to replace copper with fiber as the physical transport layer, connecting data converters to digital signal processors. The goal is to substantially simplify high-throughput data converter interconnect to enable remotely positioned converters. Exploiting lightweight optical fiber is seen as the key here, opening microwave RF systems to future innovation.

Turnkey Solid-State Amplifiers for ISM RF & Microwave Energy

While traditional RF and microwave applications are predominantly focused on wireless communication or navigation, recent advances in device technology have opened up an exciting range of non-communication, non-navigation applications of RF and microwave power. Dielectric heating is an important part of any RF and microwave heating process.

Transient EM/Circuit Co-Simulation in XFdtd®: A Closer Look at TVS Diodes for ESD Protection

TVS diodes help protect electronic circuits from surge voltages associated with an ESD event. XFdtd’s transient EM/circuit co-simulation capability combines the strength of 3D full-wave electromagnetic simulation with the flexibility of circuit solvers. This paper examines the approach, which embeds a transient nonlinear circuit solver in the full-wave simulation so that all electromagnetic phenomena are accounted for in a single time-domain simulation.
