1. An image sensor, comprising:
an image sensor pixel;
a column line configured to receive a signal from the image sensor pixel; and
a passive amplifier circuit comprising:
an input port configured to receive the signal from the column line;
an output port;
a sampling switch having a first terminal coupled to the input port and having a second terminal coupled to the output port; and
a metal-oxide-semiconductor capacitor having a gate terminal configured to receive a control signal and having source-drain terminals coupled to the output port.
