“…Two variants, referred to as CCDlike and the Hammer Shape Pixel (HSP), each with pixel pitches of 7 µm or 13 µm, were studied. The Hammer Shape Pixel design and characterisation is described in [1]. This work looks at characterisation of the 13 µm CCD-like pixel device.…”

The performance of a prototype true charge transfer imaging sensor in CMOS is investigated. The finished device is destined for use in TDI applications, especially Earth-observation, and to this end radiation tolerance must be investigated. Before this, complete characterisation is required. This work starts by looking at charge transfer inefficiency and then investigates responsivity using mean-variance techniques.

“…The camera system readout noise is 6e − . CMOS (Complementary Metal Oxide Semiconductor image sensors) [3][4][5] sensors use the CMOS process, which is most commonly used in general semiconductor circuits. Thereby, the convenience of integrating peripheral circuits (such as ADC [6], CDS, Timing generator or DSP) [7] into the sensor chip can save the cost of peripheral chips.…”

To detect faint target stars of 22nd magnitude and above, an astronomical exploration project requires its space camera’s readout noise to be less than 5e− with long-time working stability. Due to the limitation of satellite, the traditional CCD detector-based camera does not meet the requirements, including volume, weight, and power consumption. Thereby, a low-noise ultra-stable camera based on 9 K × 9 K large target surface CMOS is designed to meet the needs. For the first time, the low-noise ultra-stable camera based on CMOS detector will be applied to space astronomy projects, remote sensing imaging, resource survey, atmospheric and oceanic observation and other fields. In this paper, the design of the camera is introduced in detail, and the camera is tested for several rounds at −40 °C; it also undergoes further testing and data analysis. Tests proved super stability and that the readout noise is lower than 4.5e−. Dark current, nonlinearity and PTC indicators meet the requirements of the astronomical exploration project.
