Analog Mixed-Signal IC Design Engineer

Key Responsibilities:

1. Circuit Architecture & Design.

• Design high-speed (>100MS/s) Successive Approximation Register (SAR) ADCs for applications like 5G, radar, and data converters.
• Optimize critical blocks: capacitor DAC arrays, high-speed comparators, bootstrapped switches, and digital control logic.
• Achieve target specifications: ENOB (Effective Number of Bits), SFDR (Spurious-Free Dynamic Range), power efficiency (FOM < 10 fJ/step).

2. Performance Optimization.

• Mitigate nonlinearity via capacitor matching techniques (common-centroid, dummy units).
• Reduce kickback noise, clock jitter, and metastability in comparators.
• Develop calibration algorithms (e.g., background LMS for capacitor mismatch).

3. Process & Technology Integration.

• Implement designs in advanced nodes (FinFET 7nm/5nm, 28nm CMOS).
• Model parasitics, device mismatch, and PVT (Process-Voltage-Te...
