If you’re looking for help designing a broadband Power Amplifier (PA), the 3D Smith Chart may be just the answer for you. 3D Smith Charts can be easily generated from Keysight’s Advanced Design System (ADS) software using Python scripts. You don’t even need to know Python. A Data Link with Python in ADS provides a simple way for you to call… (Show more)

You are designing a power amplifier and have a nonlinear device model. You may want to know what load gives the maximum power-added efficiency (PAE) while the device is delivering a specified output power and while it is operating below some maximum allowable gain compression. How do you do this? Andy Howard, a Senior Application Engineer at… (Show more)

Engineers surround themselves with the best tools they can find. For the RF engineer, a new tool discussed in the literature recently is the Cylindrical 3D Smith Chart (also called the “Smith Tube”).  This 3D version of the classical Smith Chart allows engineers to explore data in new and interesting ways.   The Smith Chart was developed in the… (Show more)

Introduced in a separate post, GoldenGate 2017 enhances circuit reliability in RFIC design by checking against electrical (such as voltage and current) and geometrical rules that exist in the PDK and/or rules set by the user. This feature is referred to as safe operating area, or SOA. When GoldenGate 2017 finds out that one of these rules is not… (Show more)

GoldenGate, offered by Keysight EEsof EDA, is the best-in-class RFIC simulation tool inside the Cadence Virtuoso design environment. For many years, RF designers have relied on GoldenGate to solve their challenging problems, and have benefited from its robust simulation convergence and fast simulation capabilities to fully characterize their… (Show more)

A statistical simulation technique has become popular for the design and analysis of high-speed signals. Especially where accurate prediction of random jitter is important, such as in the measurement of eye opening at ultra-low BERs. In this DesignCon 2017 paper published by my colleagues Hee-Soo Lee, Cindy Cui, Heidi Barnes, and Luis Boluna, you… (Show more)

PCI Express Gen3 (PCIe Gen3) specifies a high-speed differential I/O interconnect that runs at 8.0 Gbps. It has many benefits, and it also presents a critical challenge. PCIe, using high-speed 8-Gbps serial links, can suffer from a large array of physical phenomena and this can lead to excessive EMI emissions in large systems. Fortunately, there… (Show more)

Python is a programming language that lets you work quickly and integrate systems more effectively. It’s been used in many areas such as Statistical Analysis, or Artificial Intelligence; and it is also very useful in Device Modeling. Today we are going to introduce the Python integration with Keysight IC-CAP device modeling platform (version 2013… (Show more)

How exactly do you simulate the RF performance of Narrowband IoT (NB-IoT), a standards-based, low-power wide area technology developed to enable a wide range of new IoT devices and services? That’s the question ASTRI— Hong Kong’s Applied Science and Technology Research Institute—faced when it discovered that the RF performance specified in the… (Show more)

Model Builder Program (MBP) is a one-stop solution that provides both automation and flexibility for silicon device modeling. MBP Script is a Java™ based scripting language, where no compilation is required at the user end. MBP Script runs equivalently on Windows and Linux. Many MBP-specific APIs(Application Program Interface) and high-efficiency… (Show more)
