Abstract
The trimming range of a reference current is extended larger than that of the related art. A semiconductor device includes a reference current generating circuit that generates a reference current. The reference current includes a first base current, a second base current base current, a second base current, a temperature compensating current, and a voltage compensating current. The first base current can be trimmed. The second base current flowing opposite to the first base current can be trimmed. The temperature compensating current flows in the same direction as the first base current and has higher temperature dependence than the first and second base currents. The voltage compensating current flows in the same direction as the first base current and depends on power supply voltages more than the base currents.
