Abstract:
A semiconductor integrated circuit includes: a plurality of current sources including a first transistor individually connected to a power source line and a bias line; and a plurality of bias blocks including a second transistor configured to constitute a current mirror circuit together with the first transistor, and to divide a reference current to be a reference of the current sources so that the reference current flows through the bias line.
