15 Common Linear Technology Interview Questions and Answers

1. Walk me through your experience designing analog circuits.

This fundamental question establishes your hands-on analog design skills and development process.

• Dos:

• Discuss spec-ing, modeling, simulating, prototyping, and testing processes.

• Share examples of challenging design problems you successfully tackled.

• Demonstrate deep analog expertise, from component selection to PCB layout considerations.

• Don’ts:

• Rely on vague, high-level descriptions of the design flow.

• Get too granular on single projects vs. showcasing breadth.

• Focus only on digital design skills without highlighting analog experience.

Example: “In my previous role at ACME Company, I designed high-speed ADC converter circuits for lidar systems. This involved extensive modeling and simulation work in Cadence to refine component selection and topology. I prototyped over 15 PCB revisions, focusing on power integrity, EMI reduction, and thermal considerations critical for precision analog performance. My final design achieved industry-leading sampling rates and SNR through careful optimization of the entire analog signal chain.”

2. How would you test an analog-to-digital converter (ADC) you designed?

This question evaluates your hands-on experience validating and troubleshooting ADCs.

• Dos:

• Discuss evaluating key ADC performance parameters like sampling rate, SNR, linearity, etc.

• Highlight using appropriate test signals and measurement equipment.

• Share example issues uncovered during ADC testing and how you addressed them.

• Don’ts:

• Describe generic validation steps without analog-specific considerations.

• Omit important equipment like function generators, logic analyzers, etc.

• Miss the opportunity to showcase in-depth ADC knowledge.

Example: “To test an ADC design, I would inject sine wave and ramp signals across a range of frequencies while capturing the digitized outputs. I would evaluate signal-to-noise ratios, total harmonic distortion, and spurious-free dynamic range using FFT analysis. I would also assess differential and integral linearity by examining the ADC transfer function using histograms. On a previous project, this testing revealed non-linearity issues that I was able to correct by adjusting internal voltage references and improving grounding.”

3. How would you improve the performance of an op-amp circuit suffering from excessive noise?

This technical question tests your analog troubleshooting abilities.

• Dos:

• Address possible sources of noise (e.g. power supplies, layout, interference, component selection).

• Suggest noise mitigation techniques like filtering, shielding, PSRR improvement.

• Share examples of how you’ve overcome op-amp noise issues.

• Don’ts:

• Identify noise sources without solutions.

• Focus solely on obvious solutions without analog design nuance.

• Avoid specifics by providing textbook noise advice.

Example: “I would first examine if the source of the noise was internal or external to the op-amp. For internal noise, I would select a low-noise precision op-amp and optimize gain settings. For external noise entering through power supplies, I would add filters and enhance PSRR with a voltage reference circuit. To address interference, I would verify proper grounding and shielding, and add low-pass RC filters on input/output lines. In the past, these techniques have helped me significantly reduce 60Hz pickup and other excess noise in op-amp circuits.”

4. What experience do you have designing circuits for radiation or extreme environments?

This behavioral question evaluates your experience engineering robust designs.

• Dos:

• Identify extreme use cases you’ve designed for (high-temp, vibration, radiation).

• Discuss component selection, derating, redundancy techniques used.

• Share testing and validation methods leveraged.

• Don’ts:

• Lack experience designing for harsh electrical environments.

• Miss the opportunity to demonstrate specialized robust design skills.

• Give vague examples lacking technical depth.

Example: “At my previous role at ADEX, I designed mixed-signal sensor modules that had to operate reliably in high radiation environments. To accomplish this, I selected rad-hard components, added redundancy with error correction, and employed shielding techniques. I conducted extensive radiation testing using particle accelerators to validate robustness. Feedback from testing allowed me to refine the design to achieve over 50Mrad total ionizing dose tolerance, meeting the mission requirements.”

5. How do you stay current on the latest technologies and trends in analog design?

This question evaluates your curiosity and passion for the field.

• Dos:

• Highlight educational sources like technical journals, conferences, online courses, etc.

• Discuss networking with experts and peers to learn.

• Share specific examples of new technologies/techniques you’ve proactively learned.

• Don’ts:

• Name generic resources without demonstrating real passion.

• Admit you mostly learn on the job without going deeper.

• Seem complacent and lacking continued learning drive.

Example: “Staying current with the latest advancements in analog design is a priority for me. I regularly read publications like IEEE JSSC and attend conferences like APEC to hear cutting-edge research presentations. I also actively experiment with new components and simulation techniques outside of work. For example, I recently completed a course on high-speed PAM signaling which provided valuable insight into applying this emerging approach.”

6. How would you explain an engineering concept or technical project to a non-engineering audience?

This question tests your ability to communicate complex technical concepts clearly and simply.

• Dos:

• Provide a specific example of simplifying an engineering topic for laymen.

• Discuss techniques like avoiding jargon, using analogies/visuals, and relating to practical use cases.

• Share positive feedback received for clear explanations.

• Don’ts:

• Answer generically without providing a specific communication example.

• Underestimate the importance of translating complex concepts for any audience.

• Forget to relate engineering to real-world applications.

Example: “When presenting my senior design project to non-engineers, I needed to explain how RFID tags work. I avoided engineering jargon and used a barcode analogy to describe how tags store data. I discussed practical applications like inventory tracking that resonated with them. I used diagrams to visually convey electromagnetic signal propagation. Multiple attendees praised my ability to break down a highly technical topic in a simple, engaging way.”

7. How do you prioritize tasks when working on multiple projects with competing deadlines?

This behavioral question tests your organization, time management, and communication skills when juggling priorities.

• Dos:

• Discuss evaluating project urgency, risks, and resource availability.

• Share tactics for task prioritization and focus like to-do lists, Kanban boards, etc.

• Highlight proactive communication with managers when balancing priorities.

• Don’ts:

• Lack a systematic approach to prioritizing workloads.

• Fail to call
