Abstract
A system for detecting high speed noise in active pixel sensors includes a photodiode for receiving low levels of light, a reset transistor, an amplifier transistor, a row select transistor, and a high-speed analog-to-digital converter. The reset transistor gate receives a reset signal, and the reset transistor drain receives a reset voltage. The amplifier transistor gate is connected to the photodiode and the reset transistor's source. The amplifier transistor receives a supply voltage at the drain terminal. The row select transistor gate terminal receives a row select signal. The row select drain terminal is connected to the amplifier transistor source terminal. The high-speed analog-to-digital converter includes an analog input port connected to the row select transistor source and a digital output port capable of resolving high-speed excitation events received by the photodiode.
