Part 1 of this FAQ reviewed the standard PN semiconductor diode, and looked at some specialized variations called the tunnel, Zener/avalanche, and Schottky diodes. Part 2 briefly explores the varactor, Gunn, and PIN diodes. Q: What about the varactor diode? A: The varactor diode (Figure 1), also called a voltage variable capacitor (VVC) or varicap […]
Instrumentation, design tools to play a strategic role in robotic design
The design of robotics systems provides a unique engineering challenge and one that requires the right design tools for the job, says Bradley Sauln, Onshape Technical Services Engineer. He says much robotic design work has converged around one class of product – CAD systems. But traditional CAD is just the beginning. Modern design shops are […]
Specialized diodes, Part 1: Tunnel, Zener/Avalanche, and Schottky diodes
There are diode varieties which do much more than just block current flow in one direction and allow it in the other; some of these special diodes have favorable attributes while others are essential in modern electronics. Every electronic engineer is familiar with the diode: it’s a basic, widely used, two-terminal semiconductor device. The diode’s […]
Tools for optimizing circuit bias
If a semiconductor or vacuum tube is to accurately reproduce or amplify signals on its input, it must have on its input a non-time-varying dc voltage, i.e. dc bias, the purpose of which is to keep the device in its linear operating range. Otherwise, the input signal to be reproduced may drive the device beyond […]
Strengthening IoT with smart cards
With the Internet of Things (IoT), industries are relying on connected devices that can interact with each other and also with processes and personnel thus helping businesses meet their goals efficiently. IoT enabled devices are being successfully used in multiple industries like manufacturing, construction, logistics, agriculture, etc. and helped to optimize assets, conserve resources and […]
June Robotics Summit will cover how to test/validate collaborative bots
It used to be that industrial robots were things that operated in guarded cells; if a human stumbled into the robot’s work envelope, the whole shebang shut down for safety reasons. Those days are gone. The new byword in robotics is collaborative — fielding robots that are safe enough to operate in close proximity to […]
How it Works: Personal Defibrillator — Design and implementation
Part 1 of the FAQ began an exploration of the first Philips AED, a very innovative personal defibrillator which completely changed the way, place, operation, user role, and time-to-administer electric-shock resuscitation, as well as the popular thinking and expectations about it. Q: What other challenges did Philips face in delivering the desired BTE waveform? A: […]
How it Works — the Personal Defibrillator: Medical basics and principles
The personal defibrillator combines sophisticated electronics with precise, adaptive control of the high-energy pulses which can re-start the heart’s beating but do so without shocking the patient to death. You’ve seen those life-saving defibrillators in offices, malls, and even homes, quietly at the ready for immediate use. When the Philips Medical Systems division of Royal […]
NVIDIA’s VP and GM of Autonomous Machines Deepu Talla kicks off keynotes at 2019 Robotics Summit
The 2019 Robotics Summit in Boston on June 5th and 6th is a premier robotics event focused on the design, development, manufacture, and delivery of commercial robotics. The Summit is co-located with the DeviceTalks event at the Seaport World Trade Center. Critical technical challenges remain when designing electronics for robotics systems particularly in the context of […]
Stress & Strain, Part 2: Implications for electronics
The mechanical strain induced on electronic components due to mechanical and thermal stress is an important aspect of their performance consistency and limitations; stress is also used to enable some materials to provide critical electronic functions. Part 1 of this FAQ looked at the basic principles and tests for material strain when stress is applied. […]
