DDR4-3200 Channel Modeling and Signal Integrity Analysis Using an FPGA

DDR4 requires tight specifications for high-speed operation, and then to ensure design margins against a target system bit error rate of 1e-16. DDR4 is now able to reach speeds of 3200 Mbps per pin with an FPGA as the memory controller. This talk shows how to model a DDR4 memory channel with an FPGA and […]

A Holistic Power Integrity Approach Reduces Board Spins, Supports System Analysis and Reduces VRM Modeling Effort

I hear many recurring complaints from engineers attending my lectures.  They can be summarized as: Continuously increased technology designs on a constant, short cycle Multilayer board spins are time consuming and expensive. Must be minimized Many key design parameters and guidelines are not provided by the semiconductor manufacturers or are inaccurate. Power electronics engineers rarely […]

Principles of Designing the Board Stackup for Electronics and Manufacturability

The designer MUST be involved in the decision making for a board stackup, as the fabricator only knows his own needs, not the needs of the signals. The stack affects the way the signals flow and so can affect many electronic aspects of the functioning circuit like layer count, field spread/interference, return current, impedance control, […]

PC Board and Interconnect Design for Low EMI

As a consultant for over 10 years, I’ve realized the root cause of many design issues revolves around the circuit board design and how the I/O and power connectors are arranged and filtered. Poor board designs and poor interconnect placement and filtering can result in radiated emissions, radiated immunity, and electrostatic discharge (ESD) compliance failures, […]

Characterizing, Troubleshooting & Mitigating Wireless and IoT Self-Generated EMI

It is fairly common to find multiple on-board sources of energy causing EMI on today’s portable, mobile, and IoT devices. The EMI from these energy sources can couple and often interferes with the receiver performance of cellular, GPS and other wireless modules. This presentation describes methods for identifying, characterizing and reducing the coupling from these […]
