Integrated circuit having bipolar-CMOS circuit.

摘要

A flip-flop includes two gates (G1, G2; 1, 2; 11, 12) each having a CMOS circuit and a bipolar circuit. One bipolar circuit related to one of the gates includes first and second bipolar transistors (Q1, Q3), and the other bipolar circuit includes third and fourth bipolar transistors (Q2, Q4). A discharge circuit (3; 21) discharges the base of the first bipolar transistor in response to a change in a second input and discharges the base of the third bipolar transistor in response to a first input. The first and second inputs are complementary inputs. A charge circuit (4; 22) charges the base of the second bipolar transistor in response to the second input and charges the base of the fourth bipolar transistor in response to the first input.
