This role focuses on precision data converter ICs.

About the role

This role involves serving as a technical authority in the architecture and design of high-resolution analog-to-digital and digital-to-analog converter ICs. You will lead the development of precision data conversion solutions from concept through silicon validation, driving system-level performance.

What you'll do

• Define and lead system-level architecture of precision data converter ICs, encompassing ADC, DAC, reference, and signal-conditioning subsystems.
• Architect high-resolution ADC topologies including SAR, delta-sigma, and pipeline, optimizing for linearity, noise floor, and power efficiency.
• Lead design of precision DAC circuits including current-steering, R-2R, and segmented architectures.
• Drive calibration and trimming strategies for offset, gain, and linearity correction.
• Lead architecture and design reviews, assessing trade-offs across resolution, speed, power, and area.
• Influence converter IP reuse strategies, design flows, and product roadmaps.

What you'll need

• MSEE with 10+ years of precision data converter IC design experience, or PhD with 8+ years.
• Proven expertise in ADC architectures: SAR, delta-sigma, or pipeline, with demonstrated silicon results.
• Working experience with DAC architectures: current-steering, R-2R, segmented, or charge-redistribution topologies.
• Deep understanding of precision performance metrics: INL, DNL, SFDR, SNR, ENOB, THD, offset drift, and gain drift.
• Track record of leading converter designs from concept through tape-out, silicon validation, and production release.
• Deep understanding of CMOS process technologies, including device matching, noise mechanisms (thermal, flicker, quantization), and layout-dependent effects.
• Proficiency with Cadence IC design suite: Virtuoso, Spectre/APS, and AMS Designer.

Nice to have

• Experience with digitally-assisted calibration techniques: background calibration, digital error correction, redundancy-based algorithms.
• Familiarity with high-speed converter design techniques including interleaving and time-interleaved ADC architectures.
• Experience with switched-capacitor circuit design and bootstrapped sampling techniques.
• Knowledge of digital interface protocols for data converters (SPI, LVDS, JESD204B/C).
• Familiarity with oversampling and noise-shaping techniques for precision applications.
