Caeleste HDR Sensor Presentation

Caeleste publishes an ICSO 2020 Presentation by Bart Dierickx, CTO & co-founder of the company, "Design of a true HDR, backside illuminated image sensor with charge domain binning:"


  1. PLS is reported to be 200:1 or 1000:1. I assume that this is the sensitivity of the charge storage node, used for high gain, compared to the sensitivity of the diode. Is that sufficient for a situation where 104 dB dynamic range is present? A bright moving object will quite quickly even saturate the storage node.

  2. Bart, 200:1 is very very low.. and that for a 15um pixel which has all sorts of real estate available.
