In-pixel kTC noise suppression using circuit techniques |
摘要 |
A circuit and method for reducing kTC noise in CMOS imagers while minimizing power dissipation is disclosed. Correlated double sampling (CDS) is performed within each pixel such that the reset voltage and the integration voltage are sampled and stored within the pixel until the voltages are forwarded to a differential amplifier for subtraction.
