Lower Power Chips: What To Watch Out For


Low-power design in advanced nodes and advanced packaging is becoming a multi-faceted, multi-disciplinary challenge, where a long list of issues need to be solved both individually and in the context of other issues. With each new leading-edge process node, and with increasingly dense packaging, the potential for problematic interactions is growing. That, in turn, can lead to poor yield, cos... » read more

Best 112G SerDes IP Architecture


Real world operation of a serializer/deserializer (SerDes) in a hyperscale data center is very demanding and requires robust performance in challenging conditions such as multitude of channel insertion loss, extreme temperature cycles, different types of packages with different trace lengths and discontinuities, etc. Hence, meeting interference tolerance (ITOL) and jitter tolerance (JTOL) compl... » read more

Hyperconnectivity’s Impact On Consumers


Do you know what hyperconnectivity is? It is already affecting you, whether you know it or not. Hyperscalers are the companies like AWS, Google, and Microsoft that build and run those enormous (aka hyperscale) data centers. If you are a designer and use the cloud, then you have at least a vague idea of what data centers are being used to handle your design. But even if you are the generic perso... » read more

Retimers Replacing Redrivers As Signal Speeds Increase


Retimers are undergoing a renaissance as new PHY protocols prove too demanding for redrivers. Redrivers and retimers both have been used to extend wired signal reach over the years. But redrivers have dominated this space due to their relative simplicity and lower cost. That balance is beginning to change. “A retimer represents three things no one wants in their system — area, cost, a... » read more

High-Fidelity Optical Edge Case Analyses For Lidar Simulation


Advanced driver assistance systems (ADAS) and autonomous vehicles (AV) rely on heavily on four main sensor modalities for perception: radars, cameras, ultrasonic and, most recently, lidars (light detection and ranging). Lidar is a crucial sensor to the ADAS toolset because it can measure precise three-dimensional images (point clouds) of everything from cars to traffic lights to pedestrians in ... » read more

Gate Drive Solutions For CoolGaN 600 V HEMTs


This paper explains the gate drive requirements for Infineon’s CoolGaN 600 V e-mode HEMTs. Various driving solutions are discussed, ranging from the standard RC-coupled driver to a new differential drive concept utilizing dedicated gate driver ICs. In half-bridge topologies, a hybrid configuration combining isolated and non-isolated drivers could be an exciting alternative. Practical applicat... » read more

CXL Signals A New Era Of Data Center Architecture


An exponential rise in data volume and traffic across the global internet infrastructure is motivating exploration of new architectures for the data center. Disaggregation and composability would move us beyond the classic architecture of the server as the unit of computing. By separating the functional components of compute, memory, storage and networking into pools, composed on-demand to matc... » read more

AiP/AiM Design For mmWave Applications — Advanced RF Front-End Design Flows From Concept To Signoff


System requirements for broad bandwidth, millimeter-wave (mmWave) spectrum, phased arrays, and integrated antennas and front-ends are evolving. The challenge for engineers will be achieving the cost, size, and performance requirements that will make these products commercially viable. All these factors align to drive next-generation component integration, which includes embedding the antenna wi... » read more

Benefits Of SiC For String Inverters


SiC MOSFETs in solar and energy storage applications have clear benefits compared to silicon technologies, addressing the pressing need for energy and cost savings, particularly when bidirectional power conversion is required. Ease of installation is one of the key features of high-power solar string inverters. It is beneficial if only two workers are needed to carry and install the system.... » read more

Bringing Reset And Power Domains Together


The Unified Power format (UPF) standard enables designers to add power intent for a design. For power management, designers typically partition a design into power domains. Interactions between these power domains are done through various power control logic, like retention logic, isolation logic, and level shifters. Designers need to validate that the power control logic does not introduce new... » read more
