This is the place to find discussions on interesting topics related to signal integrity and power integrity. This week on Tim’s Blackboard is “Convolution and Single Pulse Response.” IntroductionTwo weeks ago, in the “Dirac Delta Misnomer” post, I explained why Dirac delta function is technically a distribution. I… (Show moreShow less) Understanding the impact thermal effects can have on your circuit design is critical to being able to adequately account for them during the design process. It’s also essential to designing your circuit in an efficient way. But that’s easier said than done. A recently released video from Wolfspeed may offer you some much-needed help. The… (Show moreShow less) Many of you already know that Keysight's IC-CAP software provides an open flexible architecture that supports many industry standard and proprietary models. It also provides drivers for a range of popular test instruments required to make characterization measurements for extracting device model parameters and performing optimizations. But did you… (Show moreShow less) 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, I will resolve the arrival time inconsistency shown in the previous post. IntroductionLast week, we sent an impulse through a section of 50-Ohm, 6-inch microstrip… (Show moreShow less) Accurate and efficient modeling is critical to successful design, especially when it comes to the Static Random Access Memory (SRAM) cell, the minimum geometry devices in integrated circuit technology. Modeling such circuits has grown increasingly complex with the advent of nanometer scale process geometries. That’s because increasing process… (Show moreShow less) 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 the “Dirac Delta Misnomer.” IntroductionDid you know the famous Dirac delta function is mathematically NOT a function? Fig. 1: ADS data display representation of the Dirac… (Show moreShow less) Today we are going to talk about the different types of linear simulation tools ADS provides. ADS sets up its linear simulations into three different categories: DC, AC, and S-parameter simulation. Let’s go over each of these simulations, and how easy they are to run in ADS. 1. DC Simulation: Per Ohm’s law(V=IR), you get steady-state DC… (Show moreShow less) Welcome to Tim’s Blackboard! This is the place to find discussions on interesting topics related to signal integrity and power integrity. There is no new post this week on Tim’s Blackboard, but while you are waiting for next Wednesday to come, give this SI journal article a read. I collaborated with Signal Integrity industry's leading experts,… (Show moreShow less) 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 the “melting trace paradox.” IntroductionUnlike other famous paradoxes such as the Zeno’s paradox, where Achilles and the Tortoise are involved, the melting trace paradox is… (Show moreShow less) You successfully created a Low Pass Filter in ADS by following my example in the last blog post. Let’s build off what you know from the Low Pass Filter exercise and learn how to add flexibility to your design, including PDKS and compare an ideal schematic to a schematic with external vendor’s components. What’s a PDK? You now want to design a… (Show moreShow less) Load more items
