摘要

P It is a current source intended to be mounted between two supply terminals (20, 21). It includes a current mirror (Mi) and a heart (C1) connected to each other. The mirror (Mi) comprises a pilot transistor (T5) and at least one feedback transistor (T4). The core (C1) comprises a first transistor (T1), a second transistor (T2) and a resistor (R1). The first transistor (T1) of the core (C1) and the first feedback transistor connected together form a first branch (25). The resistor (R1) and a second feedback transistor (T3) connected form a second branch (24). The pilot transistor (T5) and the second core transistor (T2) connected form a third branch (26). These branches are to be connected between the two supply terminals. The first transistor (T1) of the core is connected to the second branch (24) between the resistor (R1) and the second feedback transistor (T3). The second transistor (T2) of the heart is connected to the first branch (25) between the first transistor (T1) of the heart and the first feedback transistor (T4). /P
