At Apple, we work every single day to craft products that enrich people’s lives. Do you love working on challenges that no one has solved yet? We have an opportunity for a detailed and extraordinarily hardworking PHY Analog/Mixed-Signal Circuit Designer. As a member of our multifaceted group, you will have the unique and great opportunity to shape upcoming products that will delight and inspire millions of Apple’s customers every day! In this role, we are the center of a PHY design effort collaborating with Platform Architecture, Logic Designers, SIPI, Layout, DV and Timing Teams, with a critical impact on delivering best in class PHY designs. You will be required to do transistor level Analog/Mixed-Signal Circuit Designs, working with Layout Teams on the physical implementation of industry leading PHY designs. The ideal candidate will have significant experience in Analog/Mixed-Signal Circuit Design.
As an Analog/Mixed-Signal Circuit Design Engineer, you will be involved with all phases of high-performance PHY designs from architectural concept to delivery of our final GDS.
- Created detailed specifications for analog / mixed signal IP
- Design analog / mixed signal IP from the high level concept to the transistor level, delivering the final GDS and required collaterals
- Supervise Layout Designers as they create the IP GDS
- Run pre silicon verification flows to ensure the design’s robustness
- Characterize the silicon and debug as needed
- BS and a minimum of 10 years relevant industry experience
- Proven understanding of all aspects of Analog/Mixed Signal Circuit Design of PHYs. TX, RX, Delay Locked Loops, Phase Interpolators, Delay Lines, Duty Cycle Correctors, reference generators, etc.
