Patent ID: 7839198

Claim:
A semiconductor integrated device comprising: a level-shifting circuit including: a first input node to which a first input signal having a first amplitude is input; a second input node to which a second input signal having the first amplitude is input; a first output node from which a first output signal having a second amplitude being larger than the first amplitude is output; and a second output node from which a second output signal having the second amplitude is output; a first current mirror circuit including: a first input-side transistor; and a first output-side transistor connected with the first output node; a second current mirror circuit including: a second input-side transistor; and a second output-side transistor connected with the second output node; a first switch circuit including: a first switching element that is series-connected with the first input-side transistor and that is controlled based on the first input signal; and a second switching element that is series-connected with the first switching element and that is controlled based on the second output signal; a second switch circuit including: a third switching element that is series-connected with the second input-side transistor and that is controlled based on the second input signal; and a fourth switching element that is series-connected with the third switching element and that is controlled based on the first output signal; a fifth switching element that is parallel-connected with the first input-side transistor and that is controlled based on the second output signal; and a sixths switching element that is parallel-connected with the second input-side transistor and that is controlled based on the first output signal.
