  • Methods and systems for increasing PSRR compensation range in an image sensor
    Patent number: 11553145
    Abstract: A method for compensating a Power Supply Rejection Ratio (PSRR) in an image sensor, the method includes receiving, by processing circuitry, at least one analog signal from an active pixels sensor (APS) array, the at least one analog signal including power supply noise, combining, by the processing circuitry, amplified power supply noise with at least one ramp signal to obtain combined power supply noise, and compensating, by the processing circuitry, the PSRR of the APS array by cancelling the power supply noise of the at least one analog signal using the combined power supply noise.
