We describe Single-Photon Avalanche Diode (SPAD), the device which employs different topologies P+ anode with p-well guard ring to protect discharging at premature level also sub-ns window minimize the dark count rate as possible to maximize the signal to noise ratio of signal. SPADs are designed to be combined with quenching pixel circuit architecture to form a fluorescence life time image sensor. A 5um, 10 um and 15um SPADs and pixels with different structures are going to implementing to check different fill factors and speed of frame rate to 400 to 500 fps. |
