Inverter and bootstrap inverter having improved output characteristics

An inverter comprising:

• a first load transistor having a gate electrode and a drain electrode that are connected to a power voltage (VDD) terminal;
• a second load transistor having a gate electrode and a drain electrode that are connected to a source electrode of the first load transistor, the second load transistor having a source electrode connected to an output terminal;
• a driving transistor having a drain electrode connected to the source electrode of the second load transistor such that the output terminal is formed, the driving transistor having a gate electrode connected to an input (Vin) terminal and having a source electrode connected to a ground (GND) terminal;
• and
• a control transistor having a drain electrode connected to the source electrode of the first load transistor, having a gate electrode connected to the input (Vin) terminal, and having a source electrode connected to the ground (GND) terminal,
• wherein when the control transistor is turned on, the source electrode of the first load transistor is connected to the ground (GND) terminal, so that a voltage of a node (P) to which the drain electrode of the second load transistor and the source electrode of the first load transistor are connected becomes approximately 0V.
