About the role

Design high-efficiency Class D power output stages for automotive and consumer audio amplifier products. You will own the switching power path from architecture through silicon validation, including gate drivers, H-bridge and BTL output stages, dead-time control, and protection circuits in high-volume production ICs. Products include both monolithic power stages and multi-chip module GaN based solutions.

Responsibilities

+ Architect and design Class D power output stages: H-bridge and BTL configurations, gate drivers, charge pumps, level shifters, dead-time control, and shoot-through protection
+ Design high-voltage switching circuits with focus on efficiency, thermal performance, and EMI compliance
+ Develop transistor-level schematics in Cadence Virtuoso and verify performance across PVT corners using SPICE simulation
+ Collaborate with systems, layout, and applications engineers to meet audio performance specifications (THD+N, IMD, ...
