Abstract: An amplification apparatus includes an amplifier having an inverting terminal, and a non-inverting terminal connected to a reset voltage node, a first capacitor connected to the inverting terminal, an input voltage being applied to the first capacitor, a second capacitor connected to the inverting terminal and an output terminal of the amplifier, and a duty-cycled resistor, connected in parallel to the second capacitor, including a first resistor. The duty-cycled resistor is configured to connect the first resistor and the inverting terminal and to disconnect the first resistor and the reset voltage node during a first time interval included in a period to complete an on-and-off cycle of the duty-cycled resistor, and disconnect the first resistor and the inverting terminal and to connect the first resistor and the reset voltage node during a second time interval included in the period.
