A temperature-dependent current generator includes a first transistor connected between first and second nodes and providing a first voltage potential at the second node that decreases first order linearly when ambient temperature increases. The generator further includes an operational amplifier having first and second input terminals and an output terminal. The first input terminal is coupled to a second voltage potential that is first order independent of the ambient temperature. The second input terminal is coupled to a third node. The generator further includes a second transistor with gate, source, and drain terminals. The gate terminal is coupled to the output terminal of the operational amplifier. One of the source and drain terminals is coupled to the third node. The generator further includes a resistor coupled between the second and the third nodes. A resistance value of the resistor is first order independent of the ambient temperature.
