Abstract
An image sensor and electronic apparatus comprise a pixel circuit configured to generate an analog signal; a vertical signal line configured to convey the analog signal from the pixel circuit; an analog amplifier circuit configured to receive the analog signal via the vertical signal line and generate an amplified signal; and a tail current boost circuit configured to modify an instantaneous gain bandwidth product of the analog amplifier circuit by temporarily modifying a tail current of the analog amplifier circuit.
