Abstract:
A current mirror, comprising:a reference branch including a first transistor having first and second conduction terminals and a control terminal, the reference branch operating to have a first current pass through the first transistor; a mirror branch including a second transistor having first and second conduction terminals and a control terminal coupled to the control terminal of the first transistor, the second terminal of the first transistor and the second terminal of the second transistor being coupled together, the mirror branch operating to have a second current pass through the second transistor that is proportional to the first current; a capacitor having a first terminal coupled to the reference branch and a second terminal; and a current amplifier having an input coupled to the second terminal of the capacitor, the current amplifier operating to provide an output current to a transistor conduction terminal in one of the reference branch and the mirror branch.
