Cirrus Logic Interview Topics

Cirrus Logic interviews candidates for analog and digital design positions to assess both technical skills and behavioral traits. The document outlines topics they assess in interviews, including discrete time signal processing, CMOS analog integrated circuit design, and digital system design. It provides examples of topics within each area and recommends textbooks to prepare. Key technical skills for analog positions are DSP and CMOS analog design, while digital positions focus on DSP and digital system design. Knowledge across all areas is beneficial but not required.

Cirrus Logic Interview Topics for Analog and Digital Design

Thanks you for taking the time to interview for an analog or digital design position at Cirrus Logic. We
interview for both behavior traits and technical skills needed for advanced mixed signal product development.
Behavior traits for these positions include good problem solving, communication, innovation, analysis, and
questioning skills. For analog design positions we look for technical skills in DSP and CMOS analog IC design.
For digital design positions we look for technical skills in DSP and digital system design. Below are some of
the details on these topics. If a candidate has recently taken graduate level courses in these areas then he or
she will usually do well in the technical interviews. Knowledge in all three areas is a nice to have.

Basic Discrete Time Signal Processing Concepts


These topics apply to both Analog and Digital Design candidates.

Analog to Digital and Digital to Analog Conversion


Sampling Theorem
Aliases
Images
Fundamentals of LTI Systems
Difference Equations
The z-Transform
Filter Poles and Zeros
Relationship between the z-plane and frequency response
Relationship between the z-plane and the step response
Basic Concepts of Decimation and Interpolation Filters
Implementing of Digital Filters (Digital Designers Only)
FIR versus IIR
Signal Quantization
Coefficient Quantization
Limit Cycles in IIR filters

A good text book is Digital Signal Processing - Principles, Algorithms, and Applications by Proakis and
Manolakis.
