Abstract
A bias current generator includes a first circuit component having a first voltage developed across a pair of terminals thereof, the first voltage decreasing as an operating temperature of the first circuit component increases. The bias current generator further includes a second circuit component having a second voltage developed across a pair of terminals thereof, the second voltage decreasing as an operating temperature of the second circuit component increases. In addition, the bias current generator includes an impedance element connected to the first circuit component and the second component, the impedance element (1) having an impedance which increases as an operating temperature of the impedance element increases, and (2) having a first current flowing therethrough, wherein a decrease in the first voltage causes a corresponding increase in the first current, and a decrease in the second voltage causes a corresponding increase in the first current. Moreover, the bias current generator includes a mirroring circuit for generating a second current which mirrors the first current flowing through the impedance element. A method for generating a bias current that counteracts the effects temperature has upon electron and hole mobility is also disclosed.
