Abstract:
A level shift circuit includes: a constant-current generation unit; a current mirror unit that flows the constant-current through first and second lines; and a level shift unit that receives first and second input signals, the first input signal being varied between first and second logic levels and having first and second potentials at the first and second logic levels respectively, the second input signal being a phase-inverted signal of the first input signal, the level shift unit producing first and second output signals that are acquired by shifting a signal level at the first logic level of the first and second input signals from the first potential to the power supply potential, the level shift unit outputting the first output signal from a node on the second line and outputting the second output signal from a node on the first line. The constant-current generation unit includes a current adjustment circuit which varies the constant current value depending on a variation in the first potential.

Claim (Index 1):
A level shift circuit comprising:\n a constant-current generation unit configured to generate a constant current on a basis of a power supply potential; a current mirror unit configured to flow said constant current through a first line and a second line; and a level shift unit configured to receive a first input signal and a second input signal being inputted, the first input signal being varied in signal level between a first logic level and a second logic level and having a first potential at said first logic level and a second potential at said second logic level, the second input signal being a phase-inverted signal of said first input signal, the level shift unit being configured to produce a first output signal and a second output signal that are acquired by shifting a signal level at said first logic level of said first input signal and said second input signal from said first potential to said power supply potential, the level shift unit being configured to output said first output signal from a node on said second line and output said second output signal from a node on said first line, wherein said constant-current generation unit includes a current adjustment circuit to which said first potential is applied, the current adjustment circuit being configured to vary a value of said constant current depending on a variation in said first potential.
