NOTES:

2. Clock duty cycle is assumed to be 50%.

3. PRNU is the maximum difference between the voltage from any single pixel and the average output voltage from all pixels of the

device under test when the array is uniformly illuminated.

4. Nonlinearity is defined as the maximum deviation from a best-fit straight line over the dark-to-white irradiance levels, as a percent

of analog output voltage (white).

5. Peak-to-peak noise is the variation of a single-pixel output under constant illumination as observed over a 5-second period.

temperature (unless otherwise noted) (see Figure 2)
