Abstract:
1. A reference current generator circuit comprising: a bias circuit configured to generate a reference current along a first current path and a second current along a second current path, the reference current and the second current being proportional; a first pair of transistors connected in series and configured to conduct the reference current in the first current path; and a second pair of transistors connected in series and configured to conduct the second current in the second current path, the second pair of transistors being coupled to the first pair of transistors to provide a collective resistance value of the second pair of transistors that is proportional to temperature, wherein each of the first pair of transistors is diode-connected, and wherein each of the second pair of transistors has a control terminal that is coupled to a respective control terminal of one of the first pair of transistors.
