Special Issue Information

Dear Colleagues,

CMOS imaging sensors for many decades bring innovation to scientific and engineering measurement tools. The advances in simulation, design and manufacture of the CMOS-integrated circuits paved the way to new scientific disciplines and greatly enhanced mature fields. One of the strands that made CMOS sensors flourish is high-speed imaging capabilities.

Advances in such disciplines as Light Detection and Ranging, Time of Flight Mass Spectrometry, pulsed neutron tomography, synchrotron and free electron laser sciences are enabled by high performance CMOS image sensors.

It is my pleasure to invite you to submit original contributions or review material to the special issue “Advances in high-speed CMOS image sensor and related technologies”. The aim of this issue is to summarise advances in the area of high-speed CMOS imaging sensors and associated disciplines. Potential topics include, but are not limited to:

  • Modelling and simulation of novel design structures for fast CMOS image sensors;
  • Semiconductor sensors for fast signal processing (SPADs, LGADs etc);
  • Advanced CMOS image sensor architectures for high-speed imaging;
  • Event driven image processing, on the fly data analysis and neural network assisted data sparsification;
  • Novel applications of high-speed CMOS image sensors

The theoretical temporal resolution limit tT of a silicon photodiode (Si PD) is 11.1 ps. We call “super temporal resolution” the temporal resolution that is shorter than that limit. To achieve this resolution, Germanium is selected as a candidate material for the photodiode (Ge PD) for visible light since the absorption coefficient of Ge for the wavelength is several tens of times higher than that of Si, allowing a very thin PD. On the other hand, the saturation drift velocity of electrons in Ge is about 2/3 of that in Si. The ratio suggests an ultra-short propagation time of electrons in the Ge PD. However, the diffusion coefficient of electrons in Ge is four times higher than that of Si. Therefore, Monte Carlo simulations were applied to analyze the temporal resolution of the Ge PD. The estimated theoretical temporal resolution limit is 0.26 ps, while the practical limit is 1.41 ps. To achieve a super temporal resolution better than 11.1 ps, the driver circuit must operate at least 100 GHz. It is thus proposed to develop, at first, a short-wavelength infrared (SWIR) ultra-high-speed image sensor with a thicker and wider Ge PD, and then gradually decrease the size along with the progress of the driver circuits.
