Senior/Principal Analog and Mixed Signal Circuit Designer for NAND Flash

Key Responsibilities:

• Responsible for the circuit design, simulation, and verification of key analog/mixed-signal modules for 3D-NAND memory, including but not limited to: 1) XDec/Page buffer/Datapath design and optimization. 2) High-Voltage (HV) Charge Pump /PUMP architecture design to meet multi-voltage domain, high efficiency, and low noise requirements. 3) High-voltage switch (HV Switch ) and HV level shifter design to support >20V high-voltage operation. 4) I/O interface circuitry (including ESD protection, drive capability matching, and signal integrity optimization).
• Establish and maintain Verilog-A behavioral models of key modules for rapid system-level simulation and verification;
• Perform array-level mixed-mode simulation , proficient in using tools such as SPICE, Spectre, and HSPICE, and combining Verilog/Verilog-AMS for large-scale circuit verification;
• Collaborate closely with the...
