Ansys Releases Software Into Open Source

Sun, 02 Jan 2022 00:00:00 -0500

It may have gone somewhat unnoticed but for the first time ever, Ansys released software into the open source late last year. The software is PyAnsys, a family of Python packages providing a new, unified programmable interface to the company’s proprietary simulation stack. Learn more about this development.

MEMS Technology Develops Industry’s First 40 Gbps DPDT Differential Switch

Wed, 26 May 2021 00:00:00 -0400

The MM5600 is a DPDT DC-20 GHz switch that can operate to 40 Gbps and well suited for differential signal switching. The integrated driver can be controlled by a serial-to-parallel interface that drives the high voltage gate lines of the switches. The design also offers a considerable 94% reduction in size when compared to conventional EM relay solutions.

Imec Develops Method for Co-Integration of GaN Half-Bridge With Drivers to Boost Performance

Tue, 18 Jun 2019 00:00:00 -0400

At PCIM 2019 last month, imec announced a functional GaN half-bridge monolithically integrated with drivers. The release described how mounted on a buck-convertor test board, the chip converts an input voltage of 48 V to an output voltage of 1 V, with a pulse width modulation signal of 1 MHz. The achievement leverages on imec’s GaN-on-SOI and GaN-on-QST® technology platforms, reducing parasitic inductance and boosting commutation speed.

Tue, 30 May 2017 00:00:00 -0400

This is the first year that NIWeek has taken place in late May instead of its normal early August time slot and switches permanently to this part of the calendar. NIWeek 2017 kicked off with new CEO Alex Davern paying tribute to Dr. T with a standing ovation from the audience. Read this summary of what happened at NIWeek 2017.

Compatibility in the Capital - IEEE EMC 2016

Sun, 31 Jul 2016 00:00:00 -0400

EMC 2016 featured Dr. Robert Scully, NASA Johnson Space Lab, kicking off the plenary session with his light hearted talk, “EMC in 2016 and Beyond: What Is It and Why Do We Care?”. As the IEEE EMC is an international organization, they periodically hold EMC outside of the US so traveled to Ottawa, Canada this year.

FCC Chairman Lays Out Innovation Based 5G Plan

Tue, 21 Jun 2016 00:00:00 -0400

FCC Chairman Tom Wheeler laid out his proposal for 5G spectrum allocation that he hopes will be approved by Congress on July 14. It is a comprehensive plan to designate spectrum in the low frequency bands, develop more mid-band frequencies in the crowed areas currently used and a gives specific focus to high frequency bands in the mmWave range. He stated that we will be the first in the world to approve these types of measures if Congress gives their approval next month.

Meeting Chiphead

Fri, 29 Jan 2016 00:00:00 -0500

It was fun meeting Chiphead for the first time at DesignCon 2016. The event covers areas such as PCB design tools, power and signal integrity, jitter and crosstalk, high-speed serial design, test and measurement tools, parallel and memory interface design, ICs, semiconductor components and more. The test/measurement, software and connector companies dominate the exhibition. As the speed of digital electronics has increased, the techniques and methods for digital and RF/microwave design have converged so it was interesting to see the similarities between the two worlds.
