DDR PHY AMS Engineer

About the role

The candidate will be a Member of the Memory I/O design team supporting the definition, specification, system simulation and implementation of future LPDDR IPs. The focus of the activity will be centered around the circuit architecture and design of critical high-speed analog and digital blocks, definition of algorithms for calibration, equalization and development of abstracted models for link performance simulations.

Responsibilities

• Contribute to the definition of circuit architecture and to the design implementation of various state-of-the-art, low power blocks, and area efficient circuits for LPDDR PHY
• Circuits for High Speed IOs that include Transmitter, Receiver – CTLE/DFE, Delay Lines, DAC, OpAmp, Comparator and voltage regulators
• Work closely with other teams to port design to different nodes while improving the overall PPA from previous generation
• Develop models for link-level statistical performance simulation of the PHY (Link Training, PHY, DRAM, DB/RCD, DFE training, Transmit Equalization)
• Documentation of the micro-architecture and algorithms, and guidance of Analog, Digital, Firmware and Verification teams on the training and verification of the circuits
• Work closely with various disciplines, especially Analog Mixed Signal design, Digital Design and Firmware, as well as Design Verification to ensure optimal implementation of the overall PHY architecture and algorithms and full coverage of the features
• Lead design liaison for post Silicon characterization and productization/volume production efforts

Requirements

• Strong experience building Memory Phys and High-speed IOs with track record of multiple successful Tape-out and productization
• Analytical thinking and inventive spirit in combination with a solid understanding of risks and risk mitigation
• Strong/effective communication skills and an enthusiastic team-first mentality

Preferred Experience

• A proven successful track record in circuit-architecture and modeling for High Speed Ios
• A proven track record of leading junior engineers to deliver complex circuits
• Solid and hands-on knowledge of algorithms and equalization/calibration/clocking techniques for high-speed circuit design
• Solid knowledge of industry-standard tools and best-in-class practices for PHY modeling, both in terms of abstracted models (e.g. Matlab/Simulink) as well as Verilog/AMS-based
• Good knowledge of IO and system integration (signaling/equalization techniques, signal integrity, power integrity)
• Ability to dig into RTL or FW code supporting the custom circuit implementation

Qualifications

• Bachelor’s or master’s degree in computer engineering/Electrical Engineering
