Bode Plots are Overrated

bode plots are overrated power integrity picotest steve sandler edi con

Control loop stability is critically important. But whether your focus is on power supply design, power integrity, or mixed-signal power system design, the Bode plot probably isn’t going to provide you with reliable or optimum design guidance. The five major reasons why Bode plots are no longer sufficient is detailed in this article.

Designing Power for Sensitive Circuits

designing power for sensitive circuits power integrity picotest steve sandler publication signal integrity journal edi con outstanding paper awardThe current focus on power integrity is related to maintaining a low and flat impedance at high-speed devices such as memory devices, FPGAs, CPUs, and SerDes transceivers. The singular goal is to ensure a stable supply voltage, within the specified range, to these high-speed devices as their load currents are dynamically changing. This article discusses Sensitivity to Power Supply Noise, Defining Sensitivity, Defining Power Supply Noise Limits, Designing a Power Supply Noise Filter and High-Accuracy Low-Noise Regulators.

EDI CON USA 2017 Celebrates High Frequency and High Speed

edi con 2017 picotest power integrity signal integrity“EDI CON is the first industry event to bring together RF, microwave, electromagnetic compatibility (EMC), electromagnetic interference (EMI) and high-speed digital design engineers and system integrators for networking, product demonstrations, training and learning opportunities. In its second year, EDI CON USA offered a unique combination of training, technical sessions, workshops and panels, with a commercial exhibition not found at similar events. Eight training courses were offered on the first day, followed by technical sessions, workshops/panels, plenary talks and an exhibition with more than 100 companies on the second and third days.”

Accurately measure ceramic capacitors by extending VNA range

Ceramic capacitors play an oversized role in circuit performance as a major contributor to voltage regulator control loop stability and power delivery network (PDN) impedance. When designing with these circuit staples, you need good impedance data over a wide frequency range. Proper measurement technique is the key to making accurate measurements. Here’s how to use two simple techniques that result in accurate, wideband, frequency measurements by extending the range of a vector-network analyzer (VNA).

Extended-Range Shunt-Thru Measurement with Steve Sandler

Video-Thumb-Extended-Range-Shunt-2017In this video, Steve Sandler shows how to simplify one of the more complicated impedance measurements. The 2-Port shunt thru measurement is powerful and accurate down to very small impedance. Using the Bode 100 you can measure power distribution network impedance and decoupling capacitors with a very wide dynamic range.
