RFIC Design Engineer
Company: Apple Inc.
Posted on: January 12, 2022
Would you like to join Apple's growing wireless silicon
development team? The wireless RFIC team architects, designs, and
validates radio transceivers integrated into complex wireless SoCs.
Our wireless organization is responsible for all aspects of
wireless silicon development that transform the user experience at
the product level, all of which is driven by a best-in-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. As an RFIC design
engineer, you will be at the center of a wireless SoC design group
with a critical impact on getting Apple's state-of-the-art wireless
connectivity solutions into hundreds of millions of products.
- Typically requires at least MS + 4 years of experience or a PhD
in the area of Analog / Mixed-Signal IC design with advanced CMOS
technology nodes. We are open to multiple experience
- Deep understanding of analog and RFIC circuit design.
- Direct tape out experience with one or more of the following
blocks: on-chip LNAs and Pas, PLL/VCO/DCO/LOGEN blocks, mixers,
baseband filters and amplifiers in deep sub-micron CMOS
- Deep understanding of analog design concepts such as analysis
of noise, linearity, mismatch, stability and other analog
- Deep understanding of CMOS device physics, RF device modeling,
device noise parameters and inductor modeling.
- Familiarity with packaging effects, supply isolations, high
frequency ESD structures, and circuit layout for optimum RF
- Familiarity with various RF transceiver architectures and their
trade-offs, as well as calibration methods used for different
- Understanding of system specifications and ability to work with
system architects to translate system requirements into circuit
requirements at IC level.
- Open to work with digital design group for an optimum partition
between digital and analog domain.
- Familiarity with the integration flows and integration
challenges of wireless SoCs.
- Familiarity with mixed-signal mode verification methodology
(SystemVerilog, AMS, Nanotime)
- Knowledge of desense issues and able to work closely with board
RF/HW/Antenna teams to optimize board layouts for desense
mitigation. Experience with desense mitigation with integrated
PMUs/DSPs (i.e. substrate isolation, return loops, package
isolation, frequency planning, etc.)
- Familiarity with Cadence Virtuoso, Spectre RF, Matlab, EM
simulation (EMX, HFSS) and similar tools.
- Experience in Si characterization and debug.
- Ability to drive strong production test/QA methodologies.
As an RFIC design engineer, you will be a key member of an RFIC
design team, researching, designing and bringing the
next-generation wireless SoCs into high-volume production at
advanced CMOS technology nodes. Responsibilities include: - Design
of analog and RF blocks inside the radio, starting from concept and
transistor-level feasibility studies. - Overseeing the layout and
verifying the design to ensure a successful tape-out. - Testing the
design and debugging the issues that may arise from early
development stages through productization. - Work with platform
architects, system groups and digital design groups to define the
requirements for RF and baseband blocks based on the system
requirements. - Work with the technology team to understand the
capabilities and limits of the technology node to achieve the
optimum performance. - Participate in defining bench bring-up and
test plans for validation and characterization of designs into mass
production. - Provide guidance on analog and RF issues across
Education & Experience
MSEE is required. PhD is preferred
