摘要
An image sensor pixel noise suppression circuit having a source follower transistor based pixel circuit, a power supply voltage and noise mirror circuit, a power supply voltage and noise gain circuit, and a comparator circuit. An output of the comparator circuit provides an image related output signal wherein the noise component of the source follower signal has been suppressed. The invention further includes a CMOS image sensor containing the image sensor pixel noise suppression circuit.
