Biasing and Analog Signals The expected analog output levels are between 0.3 V for a white, saturated, pixel and 1.3 V for a black pixel. There are two output stages, each consisting of two output amplifiers, resulting in four outputs. ...
Page 11
In Figure 11, levels are defined by the pixel array voltage supplies; for correct polarities of the signals see signals in Figure 11 are generated from the on-chip drivers. These on-chip drivers need two types of signals to generate the ...
