Timing Analog/Mixed Signal IC Design - Summer Intern 2025

Job Description

Seeking an analog/mixed-signal design intern for developing complex mixed-signal ICs for Frequency Control, Clock Generation, and other Timing applications. Many of the ICs include phase-locked loops, sigma-delta modulators, ADCs, and various other mixed-signal circuits. The individual will design transistor-level analog circuit blocks, simulate sub-system performance, create and use behavioral models of blocks, do and/or supervise physical layout, verify circuit and chip-level operation and performance, and assist with tape-out related activities. Responsibilities will also include detailed documentation, silicon evaluation and debugging, production test development support, customer support, and other activities as required for the achievement of high-volume production. 

Responsibilities  
•    Analog/mixed-signal circuit and sub-system design, analysis, and implementation (including schematic entry, simulation, layout supervision, etc.) 
•    Development and use of system-level noise models for evaluation of system-level trade-offs. Improvement of the models and re-simulation throughout the design cycle according to simulated circuit performance to ensure spec compliance of the final overall IC 
•    Development and use of behavioral models for simulation of analog and mixed-signal circuits. Verification of analog and mixed-signal sub-systems and the entire chip using transistor-level and behavioral models. 
•    Laboratory measurements and validation of ICs 
•    Assistance with the development of efficient production tests and with customer support 

Requirements

Education Requirements 
M.S. or Ph. D. in Electrical Engineering (or related)

Minimum Requirements 
•    Strong motivation to contribute to all facets of chip design from conceptualization to release to mass production 
•    Experience with analog and/or mixed-signal IC circuit design in a CAD environment 
•    Strong knowledge of analog/mixed-signal circuit concepts, simulation, and testing techniques 
•    Good verbal and written communication and presentation skills, positive attitude, and willingness to work on a team as a technical leader and mentor to junior members 
•    Working knowledge of UNIX, Matlab, and circuit simulation tools 

Additional Skills (One or more of these are highly desirable)  
•    Experience/knowledge of analog/mixed-signal techniques used in clocking and timing ICs (e.g. PLLs, charge pumps, filters, VCOs, sigma-delta modulators, XOs, multi-format output drivers, system noise analysis, spur management, layout trade-offs, etc.) 
•    Experience leading other analog/mixed-signal designers, either formally or informally 
•    Experience with IO formats such as LVDS, LVPECL, LVCMOS, CML, HCSL, etc. 
•    Low-noise analog circuit techniques 
•    Low power design and implementation techniques 
•    High-speed, high-performance analog/mixed-signal circuit design techniques 
•    Experience with IC design at geometries ranging from 130-55 nm. 
•    Competence in high-level languages (e.g. Matlab, C), scripting languages (e.g. Python, TCL, Perl, SKILL), and version control systems (e.g. SVN, SOS).
