Circuit Design Engineer

Role Summary

We are seeking an experienced Senior Analog Design Engineer to design and develop high-performance analog and mixed-signal circuits for next-generation DDR and SerDes PHY IPs targeting advanced FinFET technology nodes. The ideal candidate will have strong expertise in analog circuit architecture, transistor-level design, simulation, and silicon bring-up, with experience in process technologies such as TSMC 16nm and below.

You will work closely with layout, verification, reliability, and system teams to deliver robust, high-speed, low-power analog IPs optimized for performance, manufacturability, and yield.

Key Responsibilities

• Design and develop high-performance analog and mixed-signal circuits for DDR and SerDes PHY IPs.
• Architect and implement transmitter and receiver circuits, including:
• Feed Forward Equalizer (FFE)
• Continuous-Time Linear Equalizer (CTLE)
• Decision Feedback Equalizer (DFE)
• Design precision analog building blocks such as:
• Operational Amplifiers (Op-Amps)
• Bandgap References
• Voltage Regulators (LDOs)
• Charge Pumps
• ADCs
• PLLs
• DLLs
• Clock and Data Recovery (CDR) circuits
• Perform transistor-level schematic design and optimization for power, performance, and area (PPA).
• Conduct comprehensive simulations across all PVT corners, Monte Carlo, mismatch, and worst-case operating conditions.
• Collaborate closely with layout engineers to ensure layout-aware design and post-layout optimization.
• Work with verification, reliability, and validation teams to ensure first-pass silicon success.
• Implement ESD-aware circuit design and protection methodologies.
• Drive design-for-manufacturability (DFM), reliability, and yield improvement initiatives.
• Prepare design documentation and support IP integration, characterization, and silicon debug activities.

Required Qualifications

• Bachelor's or Master's degree in Electronics Engineering, Electrical Engineering, VLSI, or a related discipline.
• 5–12 years of experience in analog/mixed-signal IC design.
• Strong experience in designing analog circuits for DDR PHY, LPDDR PHY, GDDR PHY, HBM PHY, or SerDes PHY.
• Hands-on expertise in advanced process nodes, preferably TSMC 16nm, 12nm, 7nm, 5nm, or below.
• Strong understanding of:
• Analog circuit design fundamentals
• High-speed interfaces
• Signal integrity
• Device physics
• Process variation analysis
• Experience performing:
• Pre-layout and post-layout simulations
• PVT corner analysis
• Monte Carlo simulations
• EMIR and reliability analysis
• Good understanding of ESD protection techniques and reliability considerations.

Required Tools

• Cadence Virtuoso / Artist
• Cadence ADE
• Spectre Simulator
• EMIR and Reliability Analysis Flows
• LVS/DRC debugging and post-layout verification tools

Preferred Skills

• Experience with DDR4, DDR5, LPDDR4, LPDDR5, HBM, PCIe, Ethernet, or other high-speed interface PHYs.
• Knowledge of FinFET design methodologies and advanced CMOS technologies.
• Exposure to silicon bring-up, characterization, and lab validation.
• Strong debugging and analytical skills.
• Excellent communication and cross-functional collaboration abilities.
