Abstract: Disclosed in the present invention is a floating inverter amplifier based on capacitor stacking, which boosts a power supply of the floating inverter amplifier to 2 times VDD by means of the capacitor stacking; under such condition, a transistor in the inverter may be better turned on, and a cascode structure can be applied to an inverting amplifier operating at a low power supply voltage. Furthermore, an ADC system employing the floating inverter amplifier of the present invention can process an input signal with a common-mode voltage of VDD and an amplitude up to 2 times VDD, which effectively addresses a problem of a reduced input signal amplitude under an ultra-low voltage, thereby increasing a signal-to-noise ratio of the system.
