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)

IntroductionMuch like Sir William Henry Bragg stated, often, the recipe for new discovery entails new light, so elements can be viewed in a fresh perspective.   This week on Tim’s Blackboard, I will start with the motivation for Fourier to introduce his series, follow by his unintentionally visit to the frequency domain, and end with how the new… (Show more)

Demands for faster data speeds and more reliable services are at an all-time high. 5G is predicted to meet these demands, and much more. Although 5G is currently still in the planning stages, researchers are uncovering solutions that were previously thought impossible. Until recently, mm-waves have been viewed as unsuitable for mobile… (Show more)

This Case Study highlights work published in a recent paper in IEEE Power Electronics Magazine entitled Utilizing Modern Design Methodologies for Wide-Bandgap Power Electronics by my colleague here at Keysight EEsof EDA, Chris Mueth, and by Rakesh K. Lal of Transphorm, Inc. The high di/dt and dV/dt edges in switched-mode power supplies (SMPSs)… (Show more)

The trend in switched-mode power supplies is to use wide band gap devices because these enable a higher switching frequency and higher edge speeds (the “di/dt” of the switched loop). These two in turn enable a smaller, lighter, cheaper power supply because the energy storage capacitors and magnetics can be smaller if you top them off more… (Show more)

Welcome to Tim’s Blackboard! This is the place to find discussions on interesting topics related to signal integrity and power integrity.   This week we are taking a break from Signal Integrity. In this post, I will “demystify ultra-low impedance measurement.”   IntroductionTo measure ultra-low DC resistance, instead of using a traditional… (Show more)

         For engineering students and professionals alike, ADS simulations are a dream come true. A software that does all the calculations for me? Count me in!            As today’s circuits grow more and more complex, the processes involved in creating, testing, and simulating them tend to follow suit. RF engineers face many challenges in RF… (Show more)

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 “Your Channel, PRBS and the Eye.”   IntroductionPreviously on Tim’s Blackboard, we showed the convolution process and the helpful single pulse response. This week, we will… (Show more)
