Abstract
Analysis of dynamic-range (DR) and signal-to-noise-ratio (SNR) for high fidelity, high-dynamic-range (HDR) image sensor architectures is presented. Four architectures are considered: (i) time-to-saturation, (ii) multiple-capture, (iii) asynchronous self-reset with multiple capture, and (iv) synchronous self-reset with residue readout. The analysis takes into account circuit nonidealities such as quantization noise and the effects of limited pixel area on building block and reference signal performance and accuracy. Examples that demonstrate the behavior of SNR in the extended DR and implementation and power consumption issues for each scheme are presented.
