Signal Path
Pixel Voltage
The MT9T031 sensor analog signal path consists of the pixel array, the column sample
and hold (S/H) circuitry, the programmable gain stage, the analog offset correction and
the analog-to-digital converter (ADC).
The reset and signal voltages from the pixel are sampled onto the column sample and
hold circuitry on a row-wise basis. After signal sampling is complete, the differential
signal (reset
After the gain stage, the differential signal goes through the analog offset correction
circuitry. The user can decide if a positive or negative offset or no offset needs to be
added to the differential signal. The signal is then sampled onto the sample and hold
circuitry of the ADC before being digitized.
