Abstract
A level shift circuit includes a low voltage side circuit arranged to receive an input signal, and a high voltage side circuit arranged to output an output signal obtained by level shifting the input signal. The low voltage side circuit includes a switching transistor arranged to switch between on state and off state according to level of the input signal, and a capacitor connected in a path where current flows from the high voltage side circuit via the switching transistor. When the switching transistor switches to on state, rush current is generated, which is a transitional large current flowing through the path by the capacitor, so that level of the output signal is switched.
