Abstract
Provided are a low voltage floating inverter amplifier (LVFIA) and a switched capacitor analog-to-digital converter (ADC). The LVFIA includes a first self-biased inverter, a second self-biased inverter, and an energy-storage capacitor that are connected in parallel. The first and second self-biased inverters are clock-controlled inverters that generate a bias voltage. The parallel connection has one end connected to a supply voltage through a reset switch and the other end connected to a grounding voltage through a reset switch. An input terminal and an input terminal of the second self-biased inverter are connected to an input signal and to the grounding voltage through a reset switch. An output terminal and an output terminal of the second self-biased inverter are equipped with an amplification switch. The reset switch and the amplification switch are alternately closed. The LVFIA achieves compatibility with sub-1V power supply, reducing a power consumption and improving energy efficiency.
