Innovations in EDA Webcast Series:
UHF Broadcast: The Need for Asymmetric Doherty Power Amplifiers |
|
This webcast will discuss the advantages and disadvantages of Doherty amplification and symmetric versus asymmetric design. It will explain how an asymmetric Doherty approach can be used to design a high-efficiency, broadband PA that is suitable for UHF broadcast. Different implementations of an asymmetric Doherty approach for various frequency bands will be presented. Register for UHF webcast now.

ADS Example Book: Microwave Amplifier Design |
|
The purpose of this lab is to provide designers with a simple method of developing and designing amplifiers. Most amplifier textbooks leave a gap between theory and practical considerations. This lab combines basic amplifier design theory with practical procedures that can be used to make your design right the first time, thus minimizing your time and effort. Download the Amplifier Design Chapter from the ADS Example Book now.

How to Tune, Optimize, and Improve the Yield of a Filter |
 How do you use ADS to tune, optimize, and improve the yield of a filter? This example shows how to simulate and tune a filter's nominal response, optimize it, use Batch simulation to investigate performance, run yield analysis, and improve the yield. Registered users can download this PDF document that shows and explains some of the details.

PAM-4 Simulation to Measurement Validation With Python and ADS |
 Modern high frequency circuit simulation is complex and dealing with generated data can be challenging. In this video clip Matt Ozalas talks about directly comparing simulation with measurement by using a Virtual Instrument Software Architecture (VISA) interface. He shows an example of putting simulation data on a DCA oscilloscope for a PAM-4 waveform. View additional examples that demonstrate the power and flexibility of linking Python and ADS. |

Tim's Blackboard: Convolution and Single Pulse Response |
 This month Tim demonstrates the concept of convolution and the process of generating a single pulse response using convolution. To obtain a behavioral model for a channel, one sends an impulse (Dirac delta distribution) at the input of the channel. Because the impulse response completely characterizes the channel, the channel response at the output is the behavioral model of the channel we are looking for. Visit Tim's Blackboard to learn more.

How to Simplify Device Model Extraction Using an Open Source User Interface |
|
Our latest "How-to" video shows how one can simplify and streamline all of the most common device modeling tasks within IC-CAP. Franz Sischka illustrates the use of a custom user interface (UI) that he has been developing for many decades. We are pleased to share his wonderful UI with you. Watch video and download the UI.

Extracting Device Models Across Size, Temperature and Voltage |
 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 and tune or optimize them in one place? Learn more.

How to Estimate Voltage Spikes from Layout Parasitic Inductance in Switched-Mode Power Supplies |
|
We showed how to deal with layout parasitic inductance in our previous video “How to design DC-to-DC power converters”, but a frequently asked question was “When should I start to worry about layout parasitics inductance? Is there a quick rule of thumb that says kind of ‘Caution: Further investigation’s needed?’” The answer is yes and this follow up video is about how to make these estimates.

Mindbender |
Three boys went to their neighbor's tree to steal apples. Only one of them could climb, so that boy started to pick apples. The neighbor woke up and he came outside to investigate. The other two boys who couldn't climb got scared and ran away.
The boy up in the tree waited patiently until the neighbor left, and then got down with the apples he picked. He divided them into three equal parts and left with his share. The next day the second boy came and he saw the apples lying around. He divided them into three sections and took the share with the most apples. A few hours later the third boy arrived and took all the apples that were left. The next day when they met again, they found out they all had the same number of apples.
How could this be? How many apples were there if the boy picked fewer than 9 apples? |
