Beijing Shimo Microelectronics

Beijing Shimo Microelectronics Co., Ltd. (Cimo Micro) is a fabless semiconductor company established in 2021 that specializes in the design and sale of high-performance analog signal chain chips. The company was founded by Dr. Sun Nan, a tenured professor in the Department of Electronic Engineering at Tsinghua University, who was also named an IEEE Fellow in 2025. The leadership team is composed of internationally recognized experts and encompasses research and development, operations, quality control, marketing, and customer support.

The firm's strategic focus is on developing industrial-grade and automotive-grade signal chain integrated circuits, with a core competency in high-performance Analog-to-Digital Converters (ADCs) and Digital-to-Analog Converters (DACs). These components are crucial for bridging the gap between the analog and digital worlds. Cimo Micro's business model revolves around providing a comprehensive portfolio of signal chain chip solutions to a client base operating within the industrial automation, energy, automotive electronics, and Internet of Things (IoT) sectors. The company generates revenue through the direct sale of its semiconductor products.

Cimo Micro’s product lines include high-precision and high-speed ADCs, DACs, amplifiers, voltage reference sources, and Low-Dropout (LDO) regulators. One of its key products is the CM2249, a 16-bit, 16-channel simultaneous sampling analog data acquisition system. This system integrates features such as analog input clamp protection, anti-aliasing filters, and can process true bipolar input signals up to ±10V, making it suitable for applications like power line monitoring, multi-axis positioning systems, and data acquisition systems. The company emphasizes a full forward design methodology and mastery of manufacturing processes to ensure a domestically sourced and controllable supply chain. The company has received significant financial backing, including a Series A funding round of over 100 million yuan and a private placement of 22.5 million yuan in February 2021.
