| titleOfInvention | A Miniature Spectrometer CMOS Driving Circuit |
| abstract | A micro spectrometer CMOS drive circuit of the present invention, said micro spectrometer CMOS drive circuit is composed of USB3.0 interface, FPGA, CYUSB3014, AD9826, AD847, 74H14 and other peripheral chips. Sending the driving clock through FPGA through 74H14 can realize the driving of a micro-spectrometer CMOS detector S11639 and generate an analog video signal. The generated analog signal is collected by AD9826 after being passed by AD847 to generate a digital video signal, which is sent to the host computer through the USB3.0 interface through CYUSB3014. The host computer can send UART protocol signals to control the exposure time of S11639 and other instructions through the same USB3.0 interface. At the same time, the host computer can send I/O signals through the USB3.0 interface as an external trigger command. The invention reduces the use of driving signals and off-chip RAM, reduces the complexity of code programming, and reduces peripheral chips, thereby further reducing the size and cost of the PCB board. In addition, on the premise of not increasing the peripheral interface, an external trigger function is added to improve the accuracy of data collection. |
