摘要：A current generating circuit including a current mirror, an impedance device, afirst voltage generating portion and a second voltage generating portion. The currentmirror has a current output leg and a current generating leg. The impedance device isconnected to the current generating leg. The first voltage generating portion can

generate a first voltage that is complementary to absolute temperature. The secondvoltage generating portion can generate a second voltage that is proportional toabsolute temperature. The first voltage generating portion and the second voltagegenerating portion are arranged to generate an impedance current across the

impedance device. The current output leg is operable to output an output current basedon the impedance current. The impedance device has an impedance value, a first terminaland a second terminal. An impedance voltage drop across the first terminal and thesecond terminal is equal to a product of the impedance value and the impedance current.The first voltage is based on an attenuation of the impedance voltage drop.
