TDI型CMOS图像传感器时序控制设计与实现
Designand Implementation of Timing Control for TDI CMOS Image Sensor
摘要
Abstract
The timing control circuit of 1 024×128 time-delay-integration (TDI) CMOS image sensor was designed. The synchronization of charge transfer between pixels and signal accumulation was implemented, based on along-track-rolling exposure mode and through increasing the frequency of exposure. The timing control circuits of pixel array, accumulator and column level ADC were designed and verified. I2C bus controlled variation of the related parameters. The design costs 761 standard cells, and the layout size is 125μm× 160μm. Total dynamic power consumption is 40. 55μW, and leakage power consumption is 10. 43μW. Timing is correct and meets the requirements. The combination of timing control circuit and analog circuit implements a TDI CMOS image sensor.关键词
