Key Responsibilities: 1. Circuit Design & Development. Design high-speed analog circuits for DDR PHY interfaces (DDR4/DDR5/LPDDR5/6). Key modules: PLLs, DLLs, TX/RX channels, ODT (On-Die Termination), equalizers (CTLE/DFE), voltage regulators. Optimize power, performance, area (PPA), and signal integrity (SI). 2. Signal/Power Integrity (SI/PI) Analysis. Model and simulate channel losses, crosstalk, jitter, and eye diagrams. Ensure compliance with JEDEC standards (e.g., DDR5-6400 MT/s). Design impedance-matching networks and noise-suppression circuits. 3. Process Technology Adaptation. Implement designs in advanced nodes (FinFET, 7nm/5nm and below). Address PVT (Process-Voltage-Temperature) variations and reliability challenges (TDDB, EM/IR). Collaborate with layout engineers on floor planning, matching, and parasitic extraction. 4. Validation & Testing. Develop test plans for lab characterization and ATE (Automated Test Equipment). Debug silicon failures using oscilloscopes, BERTs, and...
