Self-biasing inverter and control method thereof

A self-biasing inverter comprising:

• a power terminal configured to receive a working power;
• an input terminal configured to receive an input signal;
• an output terminal configured to output an output signal related to the input signal;
• a first transistor electrically connected between the power terminal and the output terminal, wherein a control terminal of the first transistor is electrically connected to a node;
• a second transistor electrically connected between the output terminal and a ground terminal, wherein a control terminal of the second transistor is electrically connected to the node;
• a capacitor electrically connected between the input terminal and the node;
• a switch unit connected to the capacitor in parallel;
• and
• an impedance assembly electrically connected between the node and the output terminal;
• wherein, in a first mode, the power terminal receives the working power, the switch unit is turned-off, and the impedance assembly allows the node to be electrically connected to the output terminal through an impedance;
• in a second mode, the power terminal stops receiving the working power, the switch unit is turned-on, and the impedance assembly disconnects the node from the output terminal.
