|Proposed HCG pixel. (a) Cross-section of the proposed pixel for|
reducing the parasitic capacitance of floating diffusion. (b) Potential
diagram as a function of the voltage level of VRTH.
|Photoelectron-counting histrograms with a theoretical Poisson|
distribution of the developed CMOS imager (@ 100,000 points,
230 LSB/e− using internal ADC). (a) Signal level λ = 2.05.
(b) Signal level λ = 4.0.
This is close to 0.22e- rms noise reported in an earlier paper.
