EDA Software Design Flow Considerations For The RF/Microwave Module Designer


Miniaturization of consumer products, aerospace and defense systems, medical devices, and LED arrays has spawned the development of a technology known as the multi-chip module (MCM), which combines multiple integrated circuits (ICs), semiconductor die, and other discrete components within a unifying substrate for use as a single component. This white paper outlines the steps for implementing an... » read more

RF/Microwave EDA Software Design Flow Considerations For PA MMIC Design


In this white paper, a gallium arsenide (GaAs) pseudomorphic high-electron mobility transistor (pHEMT) power amplifier (PA) design approach is examined from a systems perspective. It highlights the design flow and its essential features for most PA design projects by illustrating a simple Class A GaAs pHEMT monolithic microwave IC (MMIC) PA design using Cadence AWR Microwave Office circuit desi... » read more

Manufacturing Bits: Jan. 3


Gallium oxide chips Looking to commercialize a promising ultra wide-bandgap technology in the market, Novel Crystal Technology (NCT) has developed a Schottky barrier diode based on a material called gallium oxide. NCT devised an ampere-class 1,200-V diode based on gallium oxide. A diode is a device that passes electricity in one direction and blocks it in the opposite direction. Still in R&... » read more

High Electron Mobility in Strained GaAs Nanowires


Abstract: "Transistor concepts based on semiconductor nanowires promise high performance, lower energy consumption and better integrability in various platforms in nanoscale dimensions. Concerning the intrinsic transport properties of electrons in nanowires, relatively high mobility values that approach those in bulk crystals have been obtained only in core/shell heterostructures, where elec... » read more

Emerging Apps And Challenges For Packaging


Advanced packaging is playing a bigger role and becoming a more viable option to develop new system-level chip designs, but it also presents chipmakers with a confusing array of options and sometimes a hefty price tag. Automotive, servers, smartphones and other systems have embraced advanced packaging in one form or another. For other applications, it's overkill, and a simpler commodity pack... » read more

RF GaN Gains Steam


Wide-bandgap semiconductors are hot topics these days. One wide-bandgap semi type--silicon carbide (SiC)--is the talk of the town and is gaining steam in electric vehicles and other systems. But let’s not forget about gallium nitride (GaN). GaN, a binary III-V material, has 10 times the breakdown field strength with double the electron mobility than silicon. GaN is used for LEDs, power ... » read more

The Future Of Power Needs To Be Exotic


Moore’s Law follows the continual advancement of smaller silicon transistors, which is ideal for faster operating speeds in processors and increasing memory size density. However, not all solutions require smaller transistors, and not all are made on silicon wafers. LEDs are made from gallium arsenide (GaAs) and lasers use indium phosphide (InP), while power devices are transitioning to si... » read more

5G Heats Up Base Stations


Before 5G can be deployed commercially on a large scale, engineers have to solve some stubborn problems—including how to make a hot technology a whole lot cooler. 5G-capable modem chipsets are already on the market from Qualcomm, Samsung, Huawei, MediaTek, Intel and Apple, with some 5G service (LTE-Advanced/LTE-Advanced Pro) available in the U.S. But still mostly missing from the 5G equati... » read more
