Nanoview launches high performance ADC chip

It is reported that since 2006 , chip products have surpassed oil to become the largest imported product in China. Since 2013 , the annual import volume has exceeded 200 billion US dollars. From the perspective of the medical industry, most of the chips used by domestic medical device manufacturers are commercial chips for purchasing foreign chip manufacturers. These chips are expensive and occupy a large part of the cost of these devices. More importantly, they are subject to Foreign chip manufacturers.

It is extremely urgent to realize the independent research and development of the chip. Chen Chuanhong, the director of the major special office of the Ministry of Science and Technology, once said: "The chip is strong and the industry is strong, and the chip is booming."

Nano-Vision is the status quo of the domestic chip industry. It has always attached great importance to the independent research and development of chips. The recent efforts have been made by the research and development department of Nano-view Chengdu. The 20MHz sampling rate and 16bit independently developed by Nano-Vision The high-performance ADC chip (Analog-to-Digital Converter) is a one-time successor. Its main performance has reached the level of similar chips of foreign top chip manufacturers. This is a historic moment for Nanoview and another milestone in the development process.

So what are the advantages of this ADC chip independently developed by NanoVision?

Small chip, great effect

The 16-bit high-performance ADC chip has four times the resolution of a 14-bit ADC, with a larger dynamic range and lower noise. For imaging applications, more image detail can be presented for more accurate image effects.

20MHz 16bit ADC dynamic performance comparison

Through comparison chart, it can be found that the nano-view design chip surpasses the performance of 20MHz 16bit ADC of a foreign top manufacturer in both SFDR and SNR core parameters, which can fully meet the needs of radiation imaging applications, and create radiation imaging "China core". On the way, I took a big step.

Skillful, multi-resistant

This ADC chip is perfectly integrated into CMOS detectors, which greatly improves product usability. After the ADC is integrated into the sensor, the easily interfered analog signal is integrated into the CMOS chip, which greatly solves the problem of multi-channel acquisition high density, can increase the number of line channels, shorten the path, and reduce the noise and anti-interference of the electronic link. Ability.

In addition, high-performance ADCs are widely used to convert analog signals from detectors into digital signals in radiation imaging products such as DR amorphous silicon detectors, CT detectors, and security line scan detectors.

At present, several international giants of radiation imaging detectors use third-party ADC chips in flat panel detectors and CMOS detectors. Nano-view masters the internal core technology of detectors and masters the independent design of key chips. Future development space and cost control capabilities will be better than international giants.

The successful verification of this chip proves the research and development strength of Nanoview. The chip technology is the core of the detector. It is the strategic high ground of the company. It is the milestone of Nanoview to create the “China Core” of radiation imaging. Our detector in the future Will rely on chip-level advantages to provide customers with better products, and contribute to the development of domestic chips.
