According to the model , circuits are designed , which include the circuit of two kinds of pixel , column output circuit , output buffer and decoder that is used to select row and column 接著再利用n + - psub型二極管的模型設(shè)計圖像傳感器的電路,包括兩種像素電路,列輸出電路,單位增益緩沖器,以及用于行列選擇的譯碼器。
This design starts from the study of principal of photo - electricity conversion of photodiode . then , the models of photodiode are established , the relationship figures of light intensity and photocurrent are achieved by using matlab , n + - psub diode is chosen as the device of photo - electricity conversion 本設(shè)計首先研究圖像傳感器的光電轉(zhuǎn)換原理,再建立光電二極管的模型,并用matlab編程計算并繪制幾種類型的二極管的光電流與光強的關(guān)系圖以及響應(yīng)率的圖,并選擇n + - psub型二極管作為光電轉(zhuǎn)換器件。
