Abstract
A current detection circuit, a semiconductor device and a semiconductor system which are capable of improving current detection accuracy are provided. According to one embodiment of the invention, a current detection circuit includes a resistive element to convert an input current supplied from outside into an input voltage, a constant-current source, a resistive element to convert an output current of the constant-current source into a reference voltage, and an AD converter to AD-convert the input voltage using the reference voltage.
