五、传感器特性的分析线转移成象传感器正像在前面一节描述的那样,由于使用了垂直汇流线的双读出,使之呈现了独特的性能。在这节中将分析这些特性。(一)瞬态噪声引入到每个加注转移的两个瞬态噪声源可分为:沟道的界面态噪声和由于沟道电阻造成的噪声,前者可通过对整个 LTD 全部采用埋沟工艺来消除,这同时也促进了电荷 Q_1和 Q_2从埋沟 CCD 寄存器向 LTD 的转移。沟道电阻噪声需作详细的分析,电荷转移在两个连续的方式下出现:强反型和弱反型。
V. ANALYSIS OF SENSOR CHARACTERISTICS Line Shifting Imaging Sensors, as described in the previous section, offer unique performance due to the dual readout of vertical busbars. In this section we will analyze these features. (A) the introduction of transient noise into each transient transfer of two transient noise sources can be divided into: the channel interface state noise and noise due to channel resistance, the former can be used by the entire LTD buried trench technology , Which also facilitates the transfer of charges Q_1 and Q_2 from the buried CCD register to LTD. The channel resistance noise needs to be analyzed in detail, and charge transfer occurs in two consecutive ways: strong inversion and weak inversion.
