Abstract
A ratio-independent switched capacitor amplifier includes a first sampling circuit configured to sample a first input voltage as a first sampling voltage and to double a level of the first sampling voltage during an interval in which the first input voltage is cut off; a second sampling circuit configured to sample a second input voltage as a second sampling voltage and to double a level of the second sampling voltage during an interval in which the second input voltage is cut off; and a differential amplifier circuit configured to output a difference between the first sampling voltage and the second sampling voltage.
