Abstract
Driving circuits (6) output driving signals to drive switching transistors (Q 15, Q16). A potential as the high level of the driving signal can be set lower than a power supply voltage (V.sub.DD) by connecting the sources of transistors (Q18, Q20) to a node (X). This configuration prevents an overshoot at a switching time and allows an improvement in a settling time. Therefore, a complementary current source circuit for a high-speed D/A converter can be provided.
