Abstract:
1. An inverter device including an input terminal and an output terminal, the inverter device configured to invert a signal from the input terminal and output an inverted signal at the output terminal, and the inverter device comprising: a diode device including a control terminal connected to the input terminal of the inverter device, an anode terminal connected to a logic high-level voltage terminal, and a cathode terminal connected to the output terminal of the inverter device; and a resistive device between the output terminal and a low-level voltage terminal, wherein the diode device is configured to turn on or off according to a voltage applied to the control terminal, wherein built-potential in the diode device is changed according to the voltage applied to the control terminal, wherein the diode device is configured to turn on when a voltage larger than the built-potential is applied between the anode terminal and the cathode terminal, and wherein when a low-level voltage is applied to the input terminal, the diode device is turned on, and a current path is formed from the logic high-level voltage terminal to the resistive device such that output a logic high-level voltage from the logic high-level voltage terminal is output to the output terminal, and when a high-level voltage is applied to the input terminal, the diode device is turned off, and a current path is formed from the low-level voltage terminal to the resistive device such that a logic low-level voltage from the logic high-level voltage terminal is output to the output terminal.
