Semiconductor integrated circuit

A semiconductor integrated circuit comprising:

• a constant current circuit including:
• a first current mirror circuit that includes a first transistor and a second transistor, and
• a second current mirror circuit that includes a third transistor that is connected to a first node to which current flows from the first transistor, and a fourth transistor that is connected to a second node to which current flows from the second transistor;
• a starter circuit including:
• a sixth transistor that uses a potential of the first node as a control voltage,
• a seventh transistor that is connected to a third node to which current flows from the sixth transistor, a gate electrode of the seventh transistor being at a ground potential,
• a capacitance element that is connected to a fourth node to which current flows from the seventh transistor, and
• a fifth transistor that uses a potential of the fourth node as a control voltage, and that supplies start-up current to the constant current circuit via the second node;
• and
• a power supply start-up circuit including an eighth transistor, of which a source electrode is fixed at a power supply voltage and a gate electrode is at the ground potential, and that supplies power from a drain electrode to the constant current circuit and the starter circuit.
