Santa Clara Valley, California, United States
Posted: Jul. 21, 2017
Weekly Hours: 40.00
In this highly visible role, you will be at the center of a silicon design group with a critical impact on getting functional products to hundreds of millions of customers quickly.
The ideal candidate will have 10+ years of RF/analog or mixed-signal design experience, with 5 years in leading RF CMOS design.* Direct experience designing and bringing into high volume production RF transceivers in deep sub-micron RFCMOS technology. This includes design of on-chip LNAs and PAs as well as calibration methods associated with such high performance wireless systems and ZIF designs. Experience should also include understanding of DFT and DFM techniques for high volume production environment.* Extensive knowledge of all or many of the following fields:
Deep understanding in system specification and able to work with system architects to translate system requirement into circuit requirement at IC level; Requires strong understanding of impact of modulation type to radio architecture and requirements.
Familiar with various RF transceiver architectures and their trade-offs; Demonstrate the capability to work with digital design group for an optimum partition between digital and analog domain;
Deep understanding of fundamentals of RF CMOS implementation, and basic building blocks, including LNAs, mixers, VCOs and DCOs, LO and PAs;
Deep understanding of RF device modeling, including but not limited to device noise parameters, inductor modeling. Insights into packaging effects, supply isolations, high frequency ESD structures, and circuit layout for optimum RF performance;
Deep understanding of device noise, mismatch, linearity, and other analog impairments
Requires strong knowledge of desense and able to work closely with board RF/HW/Antenna teams to optimize board layouts for desense mitigation. Also, has experience with desense mitigation with integrated PMUs/DSPs (i.e. substrate isolation, return loops, package isolation, frequency planning, etc).
Familiar with mix signal mode verification methodology
Extensive experience in Si characterization and debug
Ability to drive strong production test/QA methodologies.
Extensive experience in IP sourcing and management
As an RF IC design engineer, you will responsible for providing RF solutions for wireless chips. Responsibilities include:
• Work with platform architects, system groups and digital design group to define the requirements for RF and baseband blocks based on the system requirement.
• Work with technology team on process selection for the target device.
• Transistor-level feasibility studies of RF/mixed-signal circuit blocks and architectures
• Design various component blocks inside radio including RF front-ends, baseband filters/VGAs, LO/PLL circuits, data converters, and power management circuits
• Consult on RF analog issues across Apple
BSEE is required. MSEE/PhD is preferred
