Participate in defining, designing, developing, and taking to production analog and mixed-signal circuits and sub-systems within Apple integrated circuit devices. Specify, design, implement, and verify analog and mixed-signal circuits and sub-systems, including transistor-level analog circuits, mixed-signal interfaces, and digital control and signal processing blocks. Develop and run high-level simulations to validate top-level integration. Engage with cross-functional analog, digital, DV, firmware, software, SoC architecture, technology, packaging, silicon validation, production test, manufacturing, and other teams to implement the new circuits and sub-systems and drive them into production. Define production and bench-top test-plans, analyze results, and drive DOEs. Create integration guides and user documents, and generally assist with challenges in successfully implementing the new circuits and sub-systems into complex SoCs.
- BS degree in technical discipline with minimum 3 years of relevant experience.
- Experience conceptualizing, evaluating, designing, and taking to production analog and mixed-signal circuits and sub-systems for sensing and measurement. Such experience within digital-intensive SOCs is especially preferred
- Expertise in techniques for high-precision circuit design in the presence of large device mismatch and high supply noise
- Deep knowledge of device physics as it applies to semiconductor devices and manufacturing technology
- Solid understanding of ADC/DAC architectures, performance metrics, design trade-offs, and criteria for deciding which ADC/DAC designs are suitable for different applications
- Solid understanding of and experience with building block circuits for measurement sub-systems such as band-gaps, CMOS bias generators, TIAs, op-amps, filters, switched-cap circuits, LDOs, ADCs, etc.
- Solid understanding of and experience with precision analog design techniques including feedback and compensation, chopping, dynamic element matching, frequency planning, trimming/calibration, and real-time adaptive algorithms. Experience applying AI/ML to optimizing such techniques is highly valued
- Strong verbal and written communications skills and the ability to distill key issues from complex technical situations
- Experience in working with product and production test engineers to develop and validate test plans, optimize production testing, and debug sources of low-DPPM parametric yield loss
- Experience in C / MATLAB / Verilog modeling
- Proficiency in Python programming
- Experience with AI/ML, especially in applying tools and technique to any/all aspects of analog/mixed-signal circuit design and productization
These jobs might be a good fit
