Level shifter including capacitor and method of operating the same

A method of controlling a level shifter, the method comprising:

• receiving an input voltage through an input terminal;
• turning on a first transistor connected between a first node and a power source voltage and turning off a second transistor between the first node and a first ground voltage in response to a voltage level of the input voltage transitioning from a low level to a high level;
• turning off the first transistor and turning on the second transistor in response to the voltage level of the input voltage transitioning from the high level to the low level;
• and
• outputting an output voltage having a level range different from a level range of the input voltage based on a voltage of the first node,
• wherein turning on the first transistor includes applying a voltage having an anti-phase to the input voltage boosted by charges previously stored in at least one capacitor to a gate electrode of the first transistor.

A level shifting circuit, comprising:

• an input block configured to receive an input voltage through an input terminal;
• a shifting block connected to the input block through a first node and a second node, and including a first shifting transistor connected between the first node and a power source voltage and a second shifting transistor connected between the second node and the power source voltage;
• a first transistor connected in parallel with the first shifting transistor between the first node and the power source voltage;
• a second transistor and a third transistor connected in series between the first node and a first ground voltage;
• and
• at least one capacitor connected to the input block,
• wherein a voltage having an anti-phase to the input voltage is boosted by charges previously stored in the at least one capacitor and applied to a gate electrode of the first transistor, and
• wherein, when a voltage level of the input voltage transitions from a low level to a high level, the first node is connected to the power source voltage by turning on the first transistor, and the first node is disconnected from the first ground voltage by turning off the second transistor.
