ABSTRACT:
A semiconductor device includes a current mirror circuit having a plurality of transistors; a current source configured to supply a constant reference current to the current mirror circuit through a node; and a compensating circuit configured to supply a compensation current to the node to compensate for at least a part of gate leakage currents of the plurality of transistors. The compensating circuit may supply the compensation current equal to a summation of the gate leakage currents.
