Abstract
A semiconductor device includes: a constant current generating circuit unit; a first current mirror circuit unit having a constant current as an input current and generating a first mirror current as a mirror current; a level shift circuit unit including a clamp transistor between whose drain and source a first mirror current flows and to whose base a power supply voltage of the constant current generating circuit unit is applied, and a transistor that is connected in series to the clamp transistor and through which the first mirror current flows; a second current mirror circuit unit having as an input stage a transistor and having as an output stage a transistor through which a second mirror current replicating the first mirror current flows; and an error absorption circuit unit connected to a terminal for outputting the second mirror current of the output-stage transistor in the second current mirror circuit unit.
