Abstract: A current source includes a current mirror and a core connected together between two supply terminals. The current mirror comprises a pilot transistor and first and second recopy transistors. The core comprises first and second transistors and a resistance. The first transistor and the first recopy transistor are connected together to form a first branch. The resistance and the second recopy transistor are connected together to form a second branch. The pilot transistor and the second transistor are connected together to form a third branch. These branches are connected between the two supply terminals. The first transistor is linked to the second branch between the resistance and the second recopy transistor. The second transistor is connected to the first branch between the first core transistor and the first recopy transistor.

Abstract: A current source with low temperature dependence includes a reference current source and a current mirror for copying the reference source current to at least one output branch. The reference current source and the current mirror may have opposite coefficients of temperature dependence and the current mirror may be a weighted mirror. The present invention is particularly applicable to the manufacture of integrated circuits.

Abstract: A current source includes a master branch including a branch current fixing resistor, at least one slave branch, and a current mirror including a mirror transistor in each of the master and slave branches, respectively, to couple the branches. The current source may additionally include at least one of a first circuit for injecting in the current fixing resistor a current proportional to the master branch current and a second circuit for injecting in a degeneration resistor of the mirror transistor of the slave branch a current proportional to a current of the slave branch. The invention is particularly applicable to the manufacture of integrated circuits.
