abstract |
A single-photon CMOS image sensor (CIS) design based on pinned photodiode (PPD) with
multiple charge transfers and sampling is described. In the proposed pixel architecture,
the photogenerated signal is sampled non-destructively multiple times and the results
are averaged. Each signal measurement is statistically independent and by averaging,
the electronic readout noise is reduced to a level where single photons can be distinguished
reliably. A pixel design using this method was simulated in TCAD and several layouts
were generated for a 180-nm CMOS image sensor process. Using simulations, the noise
performance of the pixel was determined as a function of the number of samples, sense
node capacitance, sampling rate and transistor characteristics. The strengths and
limitations of the proposed design are discussed in detail, including the trade-off
between noise performance and readout rate and the impact of charge transfer inefficiency
(CTI). The projected performance of our first prototype device indicates that single-photon
imaging is within reach and could enable ground-breaking performances in many scientific
and industrial imaging applications. |
