Job Title: Sr. Analog Physical Design Engineer
Job Duties:
- Work on detailed column ADC circuit design, with a focus on column layout design. Collaborating with other column ADC designers to optimize column ADC’s performance with minimum silicon area.
- Conduct cross products column ADC layout comparison and IP layout development and maintenance.
- Perform RCX extraction of column circuit and critical signals parasitic analysis and propose optimized design to improve column ADC performance and image quality.
- Conduct image sensor pixel array and column ADC supply analysis using Totem or other methodologies, including worst case P2P resistor extraction, and optimize chip floorplan and power routing.
- Study design rules for new processes and provide physical design guidelines to the design team. Debug and develop Calibre svrf files when needed.
- Apply SKILL script to improve productivity and design robustness.
- Responsible for full-custom analog IC layout and physical verification (DRC/ANT/DFM/ERC/LVS) using industry-standard tools like Cadence Virtuoso and Calibre.
- Execute top-level layout and coordinate layout resources and schedules for all modules.
- Perform floor planning and placements including pad locations, power/clock domain planning, ESD, integration of AMS and digital blocks, and chip-level routing strategy.
- Lead top-level implementation from floorplan through GDS tape-out.
- Develop and maintain layout methodologies and documentation to ensure efficient and consistent design practices.
Requirements:
