Abstract:
A level shift circuit includes: a first and a second output transistor outputting voltages derived from a first and a second power source voltage, respectively; a first and a second input transistor outputting, based on a first input pulse signal, a first voltage for turning ON the first output transistor and a second voltage for turning OFF the second output transistor, respectively; a third and a fourth input transistor outputting, based on a second input pulse signal, a third voltage for turning OFF the first output transistor and a fourth voltage for turning ON the second output transistor, respectively; a first bootstrap circuit enlarging an amplitude of the first voltage and supplying the same to the first output transistor; and a first voltage compensation circuit, based on a third input pulse signal, making, at an end timing of the first input pulse signal, a voltage change in a direction opposite to that of a voltage fluctuation caused in the first voltage due to a parasitic capacitance in the first input transistor.
