Opinion: Future AI in EEE

Last week a student asked me about the scope of AI in the domain of Electrical Engineering so that he can “focus” on those for the future. A vast majority of people (even in tech!) are still not grasping the vastness of what is happening in the world of AI. Here’s my take on how AI might shape our industry, though I may look back at this post in 10 years and laugh at how far off I was!

Schematic Design: AI is going to dramatically change this. Manual schematic creation will die off. Think of tools like TI Webench but supercharged—where you type in your circuit functionality, and set parameters like cost or size, and AI will provide several optimized designs. Even BOM (Bill of Materials) selection will be automated, factoring in component availability during the design process itsel

PCB Layout: Auto routers have been bad but it was bad only because folks never put enough resources to truly build a good router. AI will integrate simulation and produce designs that already meet stringent EMI/EMC certifications. RF and High-speed designs are not black boxes anymore. It will be codified and automated by AI no matter what the complexity.

Chip Design: This area is already seeing AI deployment. AI can generate chip designs in ways that would take human teams years to discover. AI-designed chips will soon be creating the next generation of AI chips—it’s a self-accelerating process.

Firmware development: Code generators, with built-in testing, will interpret datasheets and produce solid firmware with test cases. What used to take hours or days to code could be handled by AI in minutes.

These are just some of the areas where I see AI revolutionizing embedded systems and EEE. Please understand AI won’t come for your job in the future not because it can’t do it, it will be because you can do it cheaper. My only advice to young engineers: Keep learning and evolve with the times. No field is a guaranteed safe zone with AI. Use it as a tool to grow to stay relevant! If there is interest, I can do a deeper dive into how AI might affect other EEE domains in a long-format blog post.

AI is going to reshape the future whether you like it or not. If you disagree, you’re either not paying attention or you’re simply in denial. Would love to hear your take, but it’s hard to argue against what’s already happening.

BackToBasics: Trimmer Potentiometers

Often called Trimpots, these little components are essential for fine-tuning circuits and ensuring your devices function just the way you want. A potentiometer is essentially a variable resistor, which allows you to manually adjust the resistance in a circuit. A trim pot is a type of potentiometer that’s designed for more precise, infrequent adjustments. Think of it as the control knob that you set once and forget. They are used for tuning circuits, setting reference voltages, and setting opamp gains when resistance tolerance needs to be handled post-assembly.



Trimpots have 3 terminals, two connected to the ends of a resistive element, and a third one (the wiper) that slides along the resistive track. By adjusting the wiper, you change the resistance between the wiper and each end of the resistor. What you need to remember is that there will always be a finite resistance between the terminals, it may not always be zero on one end. Refer to the datasheets for the minimum resistance or the terminal resistance for this value. When selecting trimpots, consider the same factors you’d consider when choosing a resistor like resistance tolerance, temperature variation, and power rating. What is extra would be contact variational resistance, which is the max change in contact resistance that will be encountered when the wiper moves from one place to another. We want this to be low. Good quality manufacturers also specify vibrational or shock tolerances.

They come in different shapes and types. The key one is a single turn vs multi-turn. It specifies the number of rotations you need to full resistance range. Multiturns are expensive but offer precise control of resistance for fine-tuning. It comes in open frame or sealed packages(useful in high humidity cases).

A common mistake I see among clients is using trimpots(as they are smaller) where rotary potentiometers should be used. Trimpots have a notoriously short lifespan (100-200 cycles) compared to rotary pots (about 10k cycles). Always check the datasheet for cycles! If the knob will be adjusted often, use a rotary pot.
