Framos Compares ON Semi Automotive Sensors

Framos publishes EMVA 1288 comparison of ON Semi older AR0132 and new BSI AR0136 automotive HDR CMOS sensors, both are 1.2MP and 3.75um pixel:


  1. seems 80dB DR to me: 17.3Ke full well over 1.73e noise = 10k ~ 80dB

    1. I think the read noise and full well capacity are measured at different gain settings. In order to achieve 1.7 e- read noise, the gain may need to be pretty high (20x - 30x), lowering the saturation electron count. The dynamic range maybe referring to the 1x gain condition, which gives a read noise at 1x gain of 8.3 e- (wait, what?).

  2. What is the advantage in this case? It seems that BSI bring very little improvement.
