Circuit Design Jobs

Circuit Design is the process of designing electrical circuits to create a complete electronic system. A Circuit Designer is responsible for designing circuits, testing the board and components through simulations, troubleshooting any errors, and even prototyping the board by manufacturing a few before completing the entire circuit accurately. Through this intricate process, a Circuit Designer will be able to optimize the design with their expertise and creative talent to push out an efficient product.

Circuit Designers are knowledgeable engineers with a high level understanding of electronics engineering and components that can be used in a circuit. They also possess analytical skills as they must be able to calculate loads, power consumption and sophisticated circuit architecture that involves cause and effects to produce sound results. With extensive knowledge of hardware engineering, Circuit Designers are responsible for hardware selection, board sizing, and routing of signals.

Here's some projects that our expert Circuit Designer made real:

  • Automation systems built through electronic schematics
  • Electrical systems concepted through hand sketches
  • PCB designs implemented through industry standard software
  • High level radio networks designed through detailed concept papers
  • Power efficient circuits delivered with noise reduction features

These projects use both beginner and advanced electrical engineering techniques that our expert Circuit Designers are capable of delivering. With creativity, knowledge in engineering disciplines and product optimization experience, our Circuit Designers create reliable and innovative solutions for our clients’ projects.

    Hey all I am just looking for a simple layout that will allow me to determine when both devices have been connected to the usb-c cable on both ends. It should just be a passthrough design that only monitors the CC lines for attach detection. I'm needing it to know if both ends are connected and not just 1 end of the cable. I have attached an image of my KiCad schematic of what I currently have using the INA219. However, it may be better to use a FUSB302/HUSB238 that's designed to monitor both CC pins so that it dont have to use 2 INA219's for each of my 6 usb-c input/output connectors. I plan on using a Arduino Pro Micro for the i2c communication to the FUSB302. I will be needing only 1 passthrough example that I can turn into the 6 input/outputs that I am needing. As alw...
