amplifiers with respect to power dissipation, several biasing resistors are required. This optimization results in an increase of signal
swing and dynamic range.

Digital Signals
Depending on the operation mode (master or slave), the pixel array of the image sensor requires different digital control signals. The
function of each of the signals is shown in
