    Abstract: 一種具有線性排列的數位化像素感應器(DPS),並且具有寬動態範圍和對數響應的設計,使用標準0.5u 的邏輯COMS標準製程來實現。
    數位化的像素感測器(DPS)包含了光二極體,放大器,比較器,8位元動態記憶體,一非線性斜坡訊號產生器。利用非線性斜坡訊號產生器可使類比訊號轉換成數位訊號時,能夠傭有全部的動態範圍和多重解析度的轉換(GAMMA的轉換)
    A linear Digital Pixel Sensor (DPS) with wide dynamic range and logarithmic response designed in standard 0.5-um CMOS logic process is presented. The Digital Pixel Sensor (DPS) includes a photo diode with capacitive trans-impedance amplifier, a comparator, a 8bit dynamic memory, a non-linear ramp generator. With a nonlinear ramp generator it allows the Analog-to-Digital converter operating in its full dynamic range and also enables the implementation of the ADC in multi-resolution mode.
