Analog IC Design Engineer — Audio (Class D power stages)

Job Title

Analog IC Design Engineer — Audio (Class D power stages)

Role Summary

Design high-efficiency Class D power output stages for automotive and consumer audio amplifier products. Own the switching power path from architecture through silicon validation, including gate drivers, H-bridge/BTL output stages, dead-time control, and protection circuits for production ICs and multi-chip GaN solutions.

Experience Level

Mid-level — typically 5–10+ years of analog/mixed-signal IC design experience.

Responsibilities

The role is responsible for architecture, transistor-level design, simulation, and production qualification of Class D power stages.

• 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 focused 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 specs (THD+N, IMD, SNR, PSRR, idle channel noise) and power delivery targets.
• Analyze and resolve design issues from prototype through production qualification, including EMI/EMC characterization and LC filter optimization.
• Contribute to IP reuse strategy and design methodology improvements.
• Mentor junior engineers and provide technical leadership: guide design reviews, drive architecture decisions, and establish schematic/documentation standards.

Requirements

Must-have technical skills and experience.

• 5–10+ years of analog/mixed-signal IC design experience, with demonstrated power-output-stage work.
• Experience designing gate drivers, H-bridge or BTL output configurations, dead-time control, and overcurrent/thermal protection.
• Strong understanding of high-voltage switching behavior, GaN/MOSFET/LDMOS device physics, and parasitic-aware design techniques.
• Experience with EMI mitigation in switching amplifiers (spread-spectrum modulation, slew-rate control, edge-rate optimization).
• Proficiency with Cadence Virtuoso schematic and simulation environment and SPICE-based verification across PVT corners.
• Proven experience taking designs from concept through tapeout and silicon bring-up.
• Demonstrated communication, interpersonal, and mentorship skills; ability to work cross-functionally and lead technical decisions.

Nice-to-have:

• Signal-chain experience with delta-sigma ADCs, DACs, or PWM/PDM switching modulators for audio-band applications.
• Familiarity with sampled-data circuits, loop-filter design, and quantizer architectures.
• Experience with automotive-qualified products (AEC-Q100).
• Publications or patents in audio IC design or Class D amplifier techniques.

Education Requirements

Master's degree in Electrical Engineering is specified (MS in Electrical Engineering or equivalent practical experience acceptable).
