ABSTRACT:
A circuit for generating a reference current comprises: a first current mirror configured to current-mirror based on a second current, so as to generate a first current that is substantially in inverse proportion to a variation of a power supply voltage; a current compensation unit configured to remove a variation of the first current corresponding to the variation of the power supply voltage to form a compensated first current; a second current mirror configured to generate the second current based on the compensated first current, and configured to provide the second current to the first current mirror; and a current output unit configured to output the second current as the reference current.
