What Aura Semiconductor does
Aura Semiconductor is a multinational fabless semiconductor company that designs and supplies mixed-signal integrated circuits for timing, power management, RF signal chain, MEMS, and IoT sensor applications. Founded in 2011 in Bangalore, India with principal operations in Milpitas, California and offices across Shenzhen, Shanghai, Ningbo, and Shaoxing in China, the company operates 6 R&D centers and more than 300 employees across 9 subsidiaries. Its product portfolio spans precision timing devices (jitter attenuators, IEEE1588 network synchronizers, clock generators, buffers, and real-time clocks), VRM controllers and smart power stages for data center/AI and notebook applications, RF power amplifiers and front-end modules for telecom infrastructure, AEC-Q100 qualified automotive timing products, and magnetic position sensors for IoT/smart metering applications. The portfolio includes 40+ documented SKUs with technical specifications such as sub-85fs rms jitter, 16-phase digital controllers supporting 3000A output, and 90A monolithic smart power stages.
Aura generates revenue through direct IC product sales to enterprise customers, supplemented by technology licensing and IP transfer arrangements. The company operates a sales-led go-to-market via [email protected] and a global distributor network, targeting telecom infrastructure operators, data center/server manufacturers, automotive OEMs and Tier 1 suppliers, medical device makers, and IoT/industrial integrators. Two major IP monetization events have shaped the recent capital profile: a $148 million sale of clock products and IP to SiTime Corporation in November 2023, and a September/October 2025 technology transfer of Vcore power technologies to onsemi covering international markets while Aura retains China rights. The company also holds an EE Times Silicon 60 'Startups to Watch' recognition from 2017 and maintains an export control compliance program covering China, US, and EU jurisdictions.
Leadership comprises CEO and co-founder Srinath Sridharan, CTO Augusto Marques, CSO and GM of VRM-Power Kishore Ganti, VP of International Business Development Elie Ayache, and VP of Engineering Shyam Somayajula. The company is privately held and venture-capital funded, with prior backing from Walden Riverwood Ventures and Celesta Capital. The business is legally domiciled as Ningbo Aura Semiconductor Co., Ltd. in China with a US principal office and an India subsidiary (Aura Semiconductor India Pvt. Ltd.). Post-2025, the strategic posture is increasingly weighted toward AI data center power delivery (AVSBus-compliant multiphase VRM controllers), automotive electronics (AEC-Q100 timing), and the retained Chinese Vcore market following the onsemi transaction.
