Analog/Mixed-Signal IC Design Engineer

3/2020 – 6/2025

Designed and optimized analog circuits including LDOs, bandgap references, op-amps, comparators, UVLO/POR, startup, bias and protection circuits for automotive mixed-signal ASICs.
Designed the VDD1/VDD2 LDOs for ATA6847/ATA6847L, achieving ±2% load and line regulation while optimizing stability, transient response and current consumption.
Implemented current-foldback and protection features in the ATA6847 supply regulators, achieving a combined VDD1 + VDD2 short-circuit limit of 105–135 mA, with undervoltage and overvoltage protection/detection.
Contributed to the ATA6847/ATA6847L 3-phase BLDC motor gate-driver SBC, supporting operation across 3–42 V and −40°C to +150°C, successful metal-fix redesign, tape-out, post-silicon validation and successful market release.
Designed and verified analog core blocks for the MCP16100 100 V/1 A synchronous step-down regulator, including UVLO/test-enable comparator and supply discharger, contributing to successful tape-out.
Performed transistor-level verification using Cadence Virtuoso/Spectre, including PVT, Monte Carlo, mismatch, noise, stability, PSRR and post-layout analysis; supported DRC/LVS.
Supported HV/BCD projects through PERC verification and collaborated with layout, verification and analog teams through design reviews and chip integration.
Contributed to AMS verification of the HV7374 ultrasound platform through test-case preparation, simulation and design reviews, supporting ASIC development and silicon-validation activities.
