ABSTRACT:
A precision current mirror circuit eliminates current-loss on the mirror side, and ultimately causes the current source and output current to be the same. The circuit includes a signal input/output means for outputting a current mirror of an input signal, a current control means for controlling a current difference between the input signal and an output signal of the signal input/output, mean and a current amplifier which amplifies the current, as needed, to perform the current control.
