Abstract
A reference current/voltage gnereator is insensitive to variations in power supply voltage and temperature. The operational parameters of matched current mirror transistors of the generator are effectively equalized by an auxiliary bias amplifier, whose transistors are matched with and connected to the current mirror transistors of the generator in such a manner as to maintain the same electrical parameters in each of the current mirror legs of the current generator, irrespective of variations in supply voltage. Temperature insensitivity is achieved by making the output current mirror a current that is the sum of two currents whose current paths complementary temperature coefficients.
