PMU Analog Designer

Apple • Cupertino, CA

5d

About The Position

In this role, you will be responsible for transistor-level designs of various blocks in ICs including both DC-DC converters and related auxiliary IPs. You may start with early feasibility studies of new concepts/designs and carry them through implementation, simulation, layout, and production. We work in a team environment to build sophisticated power management solutions for Apple products. Collaboration within and outside of our group is an integral part of our work: • Build concepts to overcome engineering problems in complex power systems. • Design blocks and documenting design towards formal design reviews. • Collaborate with mask design to construct layout collaterals. • Navigate through optimizations of power, area and performance or power IC designs. • Develop subcell and IP-level simulations to validate designs. • Define production and bench evaluation plans for post-silicon activities. • Take bench measurements to validate your own IC designs. • Review bench and production test results to drive bug fixes. • Complete designs considering ESD compliance of the circuits

Requirements

• BS and a minimum of 3 years of relevant industry experience.

Nice To Haves

• 3+ years of experience in industry for ICs going into production.
• Proven experience with optimization of voltage regulator high level architecture and low-level circuits; knowing which are suitable for given applications.
• Familiarity with buck, boost, LDOs, bandgaps, bias, comparators, and op-amps.
• Versed in the electrical characteristics and physical construction of capacitors and inductors.
• Qualified to review and provide feedback for printed circuit board designs from a power perspective and associated I/O.
• Device physics knowledge in regard to analog and power such as transistor operation, optimization, parasitics, and performance.
• We seek engineers skilled in analog IC design CAD tools and analysis flows to complete the designs for tapeout.
• Experience modeling circuits in Matlab, VerilogA, Python, or C for concepts prior to implementation.
• Validate analog/power designs on a lab bench using spectrum analyzers, oscilloscopes, signal generators, etc.
• Design with detailed testability; write test plans for trim and calibration; collaborate with test engineers.
