Precision Analog Data Converter Design

Overview

Architect and define next-generation data converter solutions, including high-resolution and high-speed ADCs (SAR, Sigma-Delta DT/CT, Time-Interleaved) and high-performance DACs (current steering, charge redistribution, segmented architectures). Translate system-level requirements into detailed architecture, drive end-to-end design, validation, and optimization of data converters. Serve as technical lead interfacing with system teams, customers, and cross-functional groups; mentor junior designers and advance converter design methodologies.

Responsibilities

• Translate system-level requirements (SNR, SFDR, ENOB, bandwidth, power) into detailed architecture and sub-block specifications.
• Drive end-to-end design of data converters, including front-end signal conditioning, references, clocking, high-speed sampling circuits, and precision analog cores.
• Implement calibration, linearity enhancement, and mismatch correction techniques.
• Develop system-level and behavioral models (MATLAB/Simulink, Verilog-A/AMS) to validate architecture, noise shaping, and dynamic performance.
• Lead detailed circuit design and analysis for critical blocks such as high-speed comparators, opamps, DAC elements, reference buffers, and clocking circuits.
• Analyze performance metrics (SNR, SNDR, SFDR, INL/DNL, jitter sensitivity) and correlate with silicon results.
• Drive silicon validation, debugging, and performance optimization across PVT corners.
• Provide technical leadership and interface with system teams, customers, and cross-functional stakeholders.
• Contribute to innovation and develop differentiated architectures, including patentable solutions.

Qualifications

• MS in Electrical Engineering with 12+ years, or PhD with 10+ years of experience in ADC/DAC design.
• Strong expertise across multiple data converter architectures: SAR, Sigma-Delta (DT/CT), Time-Interleaved ADCs.
• Experience with current steering and segmented DACs; proven track record in designing high-performance converters.
• Deep understanding of noise shaping, quantization noise, distortion mechanisms, and clocking/jitter impact on performance.
• Calibration techniques (background/foreground, DEM, mismatch correction).
• Experience with high-speed analog design challenges: bandwidth, settling, distortion, parasitics.
• System-level modeling and behavioral simulation proficiency (MATLAB/Simulink, Verilog-A/AMS).
• Hands-on experience with Cadence tools (Virtuoso, Spectre) and mixed-signal simulation.
• Proven ability to take converter designs from concept through silicon validation and production.
• Demonstrated innovation with patents/publications in data converter design.
• Strong communication skills with the ability to influence cross-functional teams and customers.
