13 March 2015A 4MP high-dynamic-range, low-noise CMOS image sensor
In this paper we present a 4 Megapixel high dynamic range, low dark noise and dark current CMOS image sensor, which
is ideal for high-end scientific and surveillance applications. The pixel design is based on a 4-T PPD structure. During
the readout of the pixel array, signals are first amplified, and then feed to a low- power column-parallel ADC array
which is already presented in [1]. Measurement results show that the sensor achieves a dynamic range of 96dB, a dark
noise of 1.47e- at 24fps speed. The dark current is 0.15e-/pixel/s at -20oC.
