Abstract: An image readout device includes comparator circuits. Each comparator circuit includes an amplifier, an input capacitor, an auto-zero switch, and a control capacitor. The amplifier compares a pixel signal to a reference signal to generate a comparison signal. The input capacitor receives the pixel signal or the reference signal. The auto-zero switch couples or decouples the input node and the output node of the amplifier. The control capacitor receives a respective control signal. Alternatively, the control capacitor can be replaced with a control switch. The control switch is coupled to the auto-zero switch in parallel. The control switch and the control capacitor can be omitted. Instead, the voltage level of the reference signal is adjusted to change the transition time points of the comparison signal.
