Abstract
Provided is a level shift circuit capable of converting a negative voltage level as well as a positive voltage level. The level shift circuit includes a switching transistor between an input transistor and a load, the switching transistor including a gate connected to a voltage source, and an input negative voltage level is converted into a second negative voltage level based on a voltage of the voltage source and a threshold voltage of the switching transistor.
