RFIC Layout Engineer

The Wireless SoC Radio Team designs state-of-art highly energy efficient CMOS radios, from RF to bits. To deliver these radios, our team is responsible for the design of a wide range of RF, analog, and mixed-signal blocks from RF front-end amplifiers to data converters, including baseband filters, baseband and RF phase-locked loops, crystal oscillators, and bandgap references. We are working on new technologies that transform the user experience at the product level, all of which is driven by a world-class vertically integrated engineering team spanning RF/Analog architecture and design, Systems/PHY/MAC architecture and design, VLSI/RTL design and integration, Emulation, Design Verification, Test and Validation, and FW/SW engineering. In this role, you will work closely with the RFIC design team to layout and verify custom RF and analog IP for complex SoC products. You will have a critical impact on developing Apple's state-of-the-art radios and getting them into hundreds of millions of products.

Description As an RF IC Layout Engineer, you will be a key member of a RFIC team, researching, designing and bringing the next-generation of wireless technologies into high-volume production in advanced CMOS technology nodes. Responsibilities include: Detailed transistor-level layout of RF and analog circuit blocks including LNA, mixers, PLL, LO generation, modulators, power amplifiers, ADC/DAC, baseband filters, and bandgap/bias/LDO. Block level layout through full verification flow including extraction, DRC, LVS, and DFM checking. Co-work with designers on block level floorplanning. Layout review for power/gnd routing, electromigration, signal path check, differential and IQ matching, and signal coupling.

Minimum Qualifications

• BS and 3+ years of relevant industry experience.
• FinFet experience.

Preferred Qualifications

• Experience in custom RF/analog layout for radio transceivers with knowledge of deep sub-micron CMOS.
• Knowledgeable in layout techniques for device matching, minimizing parasitics, RF shielding, and high frequency routing.
• Solid understanding of RC delay, electromigration, and coupling.
• Understanding of guard rings, DNW, PN junctions, and advanced process effects such as LOD, WPE, etc.
• High level proficiency in interpretation of CALIBRE DRC, ERC, LVS, etc. in FinFet Technology.
• Knowledge of CADENCE layout tools.
• Scripting skills in PERL or SKILL.
• Excellent communication skills.
