Aerospace sensor measurement chip

A few days ago, the first 33 self-designed ASIC chip FDC3301 was born in the 33-room ASIC lab of China Aerospace Science and Industry Corporation. “Power, observation of current, output data, performance test of all performance indicators... everything is normal!” The successful development of FDC3301 marks 33 electronic technology fields extending from the board level to the chip level. Talent teams are being used by chip users to the chip. The designers have changed.

Because traditional frequency measurement methods using FPGAs cannot meet the requirements for high-speed sampling of the output signals of the resonant beam accelerometer under large dynamic conditions, and the dependence on foreign chips is large, in order to change the status quo, 33 actively innovate and independently develop ASIC chips. design. The chip is mainly used to complete the synchronous continuous measurement of the frequency signal of the beam acceleration accelerometer, and can directly output the floating point frequency of the measured signal. Each of its performance indicators meets or exceeds the requirements of the chip specifications. It not only realizes chip integration of the original circuit, but also more importantly, its performance index has been significantly improved, quantization noise has been reduced by an order of magnitude, and it has significantly improved The dynamic characteristics of the system.

The ASIC chip can be applied to aerospace sensor frequency measurement, industrial field test and measurement systems, and the like. The successful development of the chip laid a solid foundation for the development of a new development space for 33 electronic circuits.
