Welcome to Tim’s Blackboard! This is the place to find discussions on interesting topics related to signal integrity and power integrity.   This week on Tim’s Blackboard is “Root Cause of Eye Closure,” where we study one of the root causes of eye closure. After reading the post, download the attached ADS workspace to experiment with Fourier… (Show more)

Many of you know Matt Ozalas, RF Design Engineer at Keysight Technologies, and his infamous YouTube video series, How to Design an RF Power Amplifier. I got a chance to talk to him about what he’s most excited about in the latest ADS release.   Kaelly: I heard ADS 2017 is being called the “3D release”. What 3D capabilities are you excited for?… (Show more)

LTspice  LTspice is a freeware SPICE simulator offered by Linear Technologies (now a division of Analog Devices Inc.). LTspice was originally called “SwitcherCAD” and was designed with switch-mode power supplies in mind. As a result, it is widely used in power electronics. IC-CAP may be used to generate device models based on measured data using… (Show more)

A new video by Wolfspeed demonstrates how the Wolfspeed ADS process design kit (PDK) is configured to work with the Keysight ADS electrothermal simulator to co-simulate electrical and thermal performance together.   Figure 1. Wolfspeed’s process design kits work with Keysight Technologies’ ADS electrothermal simulator to co-simulate electrical… (Show more)

A high-quality device model captures device behavior across geometry (W/L), temperature (T), drive voltage (Vdd), among numerous other input conditions. How much time do we spend trying to achieve a good fit across all these axes? What if we could easily bring up graphs of all key device targets such Vth (Threshold Voltage), Idsat (Drive Current),… (Show more)

You have a waveform that was generated in MATLAB. How do you use that waveform as the source for a circuit in Genesys?   Keysight’s RF/Microwave Synthesis and Simulation Software, Genesys understands MATLAB. The full-featured MATLAB script debugger in Genesys enables you to develop error-free, fully compatible equations for data processing,… (Show more)

Note: A more polished version of this Case Study is available in PDF format as STMicroelectronics & ESEO Use ADS To Design a 2.45 GHz Wireless Power Scavenging Circuit.   Previously I posted a Case Study about a wireless power scavenging circuit whose impedance matching circuit was built around a high Q quartz crystal resonator. This particular… (Show more)
