Abstract
A pixel of a pixel array is provided. The pixel includes a low frequency path configured to receive an input signal from a corresponding photodetector. The low frequency path includes a passive imaging circuit provided along the low frequency path, the passive imaging circuit configured to output an analog imaging signal and a flash analog to digital converter (ADC) that receives the analog imaging signal and processes the analog imaging signal to output a coarse digitized signal.
