本研究以高動態的光電二極體作為影像感測器之感光元件,透過數位式二次相關取樣電路消除雜訊,並設計以取樣頻率65 kHz的十位元行並列式單斜率架構作為類比數位轉換器,整合周邊電路於同一晶片中。
使用TSMC 0.18 μm CMOS標準製程下,以64x36影像陣列,驗證在Full HD的影像規格下,可達到30 frame/s的畫面更新率的影像感測系統。
量測結果顯示感光元件最低能偵測至0.5 lux的光源,高照度下電壓變化具有對數形式且動態範圍超過90 dB,影像陣列可偵測強度變化劇烈的入射光。
In this work, an image sensor with photovoltage-sensing pixels is designed and fabricated. A digital correlated double sampling circuit is designed to cancel fixed pattern noise. The implemented column-level ADC uses a single-slope architecture with 10-bit resolution and 65 kHz sampling rate. All devices and circuits are integrated and implemented in a single chip.
A 64x36 image array was fabricated with TSMC 0.18 μm CMOS technology. The array was designed for the specification of 30 frame/s in full HD.
Measurement showed that the photodiode can respond to illuminance as low as 0.5 lux. At high light intensity, photodiode voltage change in log scale and the overall dynamic range is over 90 dB. The image array can respond to wide dynamic range of incident light.
