Sigma Designs, Inc. was a fabless semiconductor company headquartered in Santa Clara, California. Founded in 1982, the firm focused on the design and marketing of system-on-chip (SoC) solutions for consumer electronics and smart home applications. Over its history, Sigma Designs developed a portfolio of multimedia processors, wireless connectivity chips, and low-power video surveillance SoCs, serving original equipment manufacturers (OEMs), original design manufacturers (ODMs) and value-added resellers worldwide.
The company’s product lines included high-performance media processors for streaming set-top boxes, Blu-ray players and networked media adapters, as well as networking solutions based on technologies such as Z-Wave, Wi-Fi and Ethernet. These chips enabled energy-efficient operation and advanced multimedia experiences in home entertainment, security systems and Internet of Things (IoT) devices. Sigma Designs also offered development tools, reference designs and software stacks to accelerate time to market for its customers.
Serving markets across North America, Europe and Asia, Sigma Designs cultivated partnerships with leading consumer electronics brands and smart home integrators. In March 2016, Thinh Tran was appointed President and Chief Executive Officer, guiding the company’s strategic focus on next-generation home connectivity and multimedia solutions. Under his leadership, Sigma Designs continued to expand its reach in the IoT and surveillance sectors.
In April 2022, Sigma Designs was acquired by Silicon Labs, a fellow provider of mixed-signal semiconductors and software for IoT applications. The acquisition integrated Sigma’s multimedia and networking product lines into Silicon Labs’ portfolio, marking the conclusion of Sigma Designs’ operations as an independent public company.
