ABSTRACT:
A detection circuit that reduces circuit scale. A plurality of current amplifiers respectively generate a plurality of detection signals corresponding to current flowing to a plurality of resistors. An error amplifier coupled to the plurality of current amplifiers compares the plurality of detection signals with a plurality of reference signals, respectively, to generate an error signal based on the comparison.
