摘要： The invention is directed generally to a correlated double-sampling (CDS) circuit using a smaller number of capacitors than conventional circuits. In embodiments of the invention, a first portion of the CDS circuit uses just two capacitors to sample the reset voltage, amplify the sampled reset voltage, and subtract a first reference voltage from the amplified reset voltage. A second portion of the CDS circuit uses just two capacitors to sample the signal voltage, amplify the sampled signal voltage, and subtract a second reference voltage from the amplified signal voltage. Embodiments of the invention also provide a cyclic analog-to-digital converter (ADC) including the CDS circuit.

摘要： An image sensor includes a delta-sigma analog-to-digital converter (ADC) including a delta-sigma modulator (DSM) and a voltage adjusting circuit. The DSM is configured to perform delta-sigma modulation on an analog signal from a unit pixel. The delta-sigma ADC is configured to convert the analog signal to a digital signal. The voltage adjusting circuit includes a replica inverter having a same configuration as at least one inverter included in the DSM. The voltage adjusting circuit is configured to adjust a power supply voltage and an input voltage provided to the at least one inverter based on a current flowing in the replica inverter.

摘要： A complementary metal oxide semiconductor (CMOS) image sensor includes a photodiode, a switch and a comparator. The switch transfers a sensing signal to a sensing node from the photodiode. The comparator, which is directly connected to the sensing node, compares the sensing signal of the sensing node with a reference signal. The comparator outputs a signal corresponding to a voltage difference between the sensing signal and the reference signal.
