I am really not going to be surprised if one day a truly archaic technology or computing language turns out to have... blogs message boards chat Formula E racing in Brooklyn: My hometown Steve Taranovich, Editor-in-Chief, Planet Analog, 6/16/2018 Comment now I have received an invitation by ROHM to a Paddock Tour which will be held at the venue of Formula E in their Brooklyn, New York race on July 12. This is part of the event's worldwide racing tour. A real Power Op Amp: 900V at 1,700 V/us Steve Taranovich, Editor-in-Chief, Planet Analog, 6/16/2018 Comment now APEX Microtechnology in Tucson, AZ does it again. This talented design team has just introduced the PA194 Power Op Amp. New tutorial tools for analog design: Op Amp and ADC Cookbooks Steve Taranovich, Editor-in-Chief, Planet Analog, 6/16/2018 Comment now Today's circuit designers usually will need to design with analog circuitry on their boards, even if the core circuitry is Processor-based or a power supply design, MEMS/sensor or such. The problem is that the great majority of designers out there are not necessarily analog experts and can probably design a basic analog solution, but not an optimally ... Seemingly Simple Circuits: Transresistance Amplifier, Part 1-- Approximating Op-Amps Dennis Feucht, Electronics Engineer, 6/16/2018 Comment now A seemingly simple circuit with only two components, an op-amp and a feedback resistor, is commonly used to convert a current to a voltage. This circuit is familiar as a photodetector or impedance-meter current-sense amplifier. The circuit is shown below, where the input capacitance of the op-amp, Ci is shown externally for analysis. Op-amps have ... Hysteretic Control: An old technology makes a comeback Scott Deuty, Power Electronics Expert, 6/12/2018 Comment now 6 comments One reason I like to write this blog is because it allows me to research new areas of power and analog electronics. Another reason I value the research is I have the opportunity to simplify electronics especially for the hobbyist and beginner. Recently, I found that the area of hysteretic control offered me a change to look in a new area that ... Most recent post, PaulChau, 6/19/2018 10:20:27 PM There is a lot of potential in this world right now that remains totally untapped.... Flex circuits in deep space Steve Taranovich, Editor-in-Chief, Planet Analog, 6/11/2018 Comment now While at this year's Space Tech Expo in Pasadena, CA last month, I had the pleasure to visit with Pioneer Circuits, Inc. who have done some amazing work with flexible circuitry in deep space. They are the 4th largest consumer of Dupont Materials in the US for military and Space applications. Pocket-Size White Noise Generator for Quickly Testing Circuit Signal Response Steve Taranovich, Editor-in-Chief, Planet Analog, 6/11/2018 Comment now Editor's note: I am pleased to bring you this month's Rarely Asked Questions (RAQ) blog by Aaron Shultz and Peter Haak, Analog Devices Oscilloscope Trigger Generators: Precision Synchronizers Dennis Feucht, Electronics Engineer, 6/10/2018 Comment now Oscilloscope triggering circuits can be adapted to other applications, as precision synchronizers. Both analog and digital 'scope triggering has been enhanced by various auto-trigger schemes. This tutorial overview of 'scope triggering circuits and schemes presents the basics of trigger generators and also some enhancements. Designing with Chip Capacitors for High-Voltage Safety and Reliability Rudy Ramos, Technical Content Marketing Project Manager, Mouser Electronics, 6/3/2018 Comment now High-voltage Multi-Layer Ceramic Capacitors (MLCCs) are great for roles such as coupling, DC blocking, snubbing, or power-supply resonators. Their high volumetric efficiency delivers high capacitance values and high breakdown voltage within compact dimensions. A 1206 (imperial: 0.125" x 0.063") chip-size MLCC can provide several thousand picofarads and a ... Journeying a long way from 1972 PONG Steve Taranovich, Editor-in-Chief, Planet Analog, 6/3/2018 Comment now Before PC-based gaming platforms like today's Portal 2, The Witcher 3: Wild Hunt, Minecraft ----even before disc-based systems like PlayStation, Xbox and Wii and as far back as Pac-Man and Donkey Kong became the obsession of millions of electronic gamers, it was Ted Dabney, one of the founders of Atari and also a creator of PONG who first made it ...

PaulChau on Hysteretic Control: An old technology makes a comeback 6/19/2018 7:42:06 PM Re: Hysteretic Converter Control: Thanks D, I am reverse engineering a similar design that's in a "deterrent". The more I look into the hysteretic control, the more I realize that there isn't much written about this interesting technology. Anything that you can... Effective-Technical-Writing dot com on Hysteretic Control: An old technology makes a comeback 6/14/2018 7:34:56 PM Re: Hysteretic Converter Control: Many thanks for your insights Dennis. We look forward to hearing more about this project steve.taranovich on Hysteretic Control: An old technology makes a comeback 6/13/2018 10:32:55 PM Re: Hysteretic Converter Control: Steve, I live on a jungle hilltop, miles from a paved road or utilities. Consequently, the inverter is of direct interest. I cannot bring myself (like my non-engineer fellow neighbor homesteaders) to buy an expensive "boat anchor" inverter... D Feucht on Hysteretic Control: An old technology makes a comeback 6/13/2018 12:12:20 PM Re: Hysteretic Converter Control: Hi Dennis, I would love an article on the "Volks-inverter" for off-grid residential use---we could use that on EDN. Would this be something that you would use in your remote location in the 'Boondocks" (Originally meaning a mountain)? steve.taranovich on Hysteretic Control: An old technology makes a comeback 6/12/2018 4:40:59 PM Hysteretic Converter Control: Scott, I share your interest in the return of hysteretic control of converters, but I don't think loop compensation need be as complicated as Maniktala makes it out to be. I am presently designing a "Volks-inverter" for off-grid residential...

How much is that difficulty offset by Mars' reduced gravity? I will go and look up the numbers but I suspect the relationship won't necessarily be linear. RobTheNob on Mars 2020 Rover will carry a drone Copter 5/23/2018 7:30:54 AM Super cool!: Thank for sharing this Steve! What an incredible mission! I am excited to see how the mission goes.
