BiMOS semiconductor integrated circuit having boosted voltage line

摘要

A BiMOS semiconductor integrated circuit such a BiCMOS circuit and a BiNMOS circuit includes a boosing section (2) and circuit section (8). The boosting section (2) is connected to a first power supply line (11) having a first potential and boosts the first potential to supply the boosted potential as a second potential on a second power supply line (12). The circuit section (8) includes an output section (6) and a logic calculation section (4). The output section (6) is connected to an output terminal (16) and the first power supply line (11) and including a bipolar transistor (32; 52). One of an emitter and an collector of the bipolar transistor (32; 52) is connected to the first power supply line (11) and the other being connected to the output terminal. The logic calculation section (4) is connected to the second power supply line (12) and one or more input terminals (14), and includes a plurality of MOS FETs (22 to 26; 42 to 44). The logic calculation section (4) performes a logic calculation on input signal supplied to the one or more input terminals (14) and selectively driving the bipolar transistor (32; 52) in accordance with the logic calculation result by passing the base current to the base of the bipolar transistor (32; 52) from said second power supply line (12).
