| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Ramp analog-to-digital converters (ADC) have been widely used for column-parallel ADCs in imagers for several reasons: simple implementation, low power consumption, and guarantee of high linearity and monotonicity. One drawback to using a ramp ADC is its slow operation speed when bit resolution is increased. In this paper we propose an accelerated ramp scheme based on photon shot noise limited characteristics of an image signal. Influence of the accelerated ramp-to-image quality was investigated by simulation, which confirmed its effectiveness. The scheme was successfully demonstrated by fabricating a prototype imager with 12-bit column-parallel ADCs. | |
