Precision Analog Data Converter Design

Job Responsibility:

Architect and define next-generation data converter solutions, including:

High-resolution and high-speed ADCs (SAR, Sigma-Delta(Discrete Time and Continuous time), Time-Interleaved)

High-performance DACs (current steering, charge redistribution, segmented architectures)

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, and clocking

High-speed sampling circuits and precision analog core

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

DAC mismatch and ADC linearity

Perform deep analysis of performance metrics (SNR, SNDR, SFDR, INL/DNL, jitter sensitivity) and correlate with silicon results Drive silicon validation, debug, and performance optimization across PVT corners Serve as technical lead and interface with system teams, customers, and cross-functional stakeholders Mentor junior designers and build technical depth in converter design methodologies across the organization Drive innovation and develop differentiated architectures, including patentable solutions
