Sensors | Free FullText | Toward the Super Temporal ...

To achieve a super temporal resolution better than ps, the driver circuit must operate at least 100 GHz. It is thus proposed to develop, at first, a shortwavelength infrared (SWIR) ultrahighspeed image sensor with a thicker and wider Ge PD, and then gradually decrease the size along with the progress of the driver circuits. The theoretical temporal resolution limit tT of a silicon ...

Analysis of Temporal Noise in CMOS APS

In a CCD image sensor, temporal noise is well studied and It is primarily due to the photodetector shot noise and the thermal and 1/f noise of the output charge to voltage amplifier. In a CMOS APS several additional sources contribute to temporal noise. These include the thermal, shot, and 1/f noise of the pixel reset, follower, and access transistors. Hand analysis of ...


SAL seeker with spatial and temporal sensors PatSnap

Therefore, a second sensor is needed. Here, a wide FOV temporal sensor is used to capture accurate laser pulse time of arrival at a 10 nanosecond resolution, if needed. Thus, the system provides degree accuracy at 300 Hz rotation rate in 22 μseconds. The output of the system of the present disclosure using both a spatial and a temporal sensor provides both PRF (pulse repetition frequency ...


Analysis of temporal noise in CMOS photodiode active pixel ...

In a CCD image sensor, temporal noise is primarily due to the photodetector shot noise and the output amplifier thermal and 1 noise. CMOS image sensors suffer from higher noise than CCDs due to the additional pixel and column amplifier transistor thermal and 1 noise. Noise analysis is further complicated by the timevarying circuit models, the fact that the reset transistor operates in ...
