Caeleste Updates on its Low Noise Pixels

Caeleste updates on the recent progress in its low noise pixels based on the combination of oversampling and inversion-accumulation cycling:

"Pixel with thin gate oxide narrow pmos amplifier has the lowest noise. Because of process variation, even the same kind of pixels has some noise difference. For pixels with thin gate oxide narrow pmos amplifier, the best pixel can reach 0.21 e-RMS read noise."
