RFIC Design Engineer - PLL
- Cupertino, CA
Posted: Mar 3, 2021
Weekly Hours: 40
Role Number: 200204885
Would you like to join Apple's fast-growing mmWave and cellular wireless design team? Do you love working on technical challenges no one has solved yet? We have an opportunity for a talented RF and PLL designer to open up the boundaries and craft novel techniques that overcome traditional circuit and architecture bottlenecks. In this role you will have the opportunity to do innovative development in PLL and transceiver design while working closely with systems and product teams at Apple. Come join us and make a critical impact on getting products to millions of customers!
- Innovative and out of the box thinking to solve challenging and difficult problems.
- Deep understanding of overall RF system and circuit level requirements.
- Hands-on experience with PLL top-to-bottom level spice and mixed mode design and simulation.
- Strong knowledge of RF architecture and blocks such as transceivers, VCOs, LNA and up/down converters. Good knowledge of ADC/DAC designs/architectures would be helpful too.
- Experience in Matlab/VerilogA modeling and strong device physics knowledge as it applies to analog IC designs.
- Working knowledge of bandgaps, bias, opamps, LDOs, feedback and compensations techniques is a bonus.
- Bring-up and debugging skills, experience in working with production test engineers to create test plans and design for testability.
• Design Charge-pump-based PLLs, Fractional-N PLLs, Digital PLLs, XTAL oscillators, and LO generation circuits. • Conduct high speed digital circuit design and timing/phase noise analysis. • Create behavioral models of PLL to drive architectural decisions and derive block-level requirements for analog and digital blocks. • Work closely with mask design team to implement layout view of designs. • Construct lab and ATE test plans; take measurements/debug for characterization and volume production.
