ABSTRACT:
A semiconductor integrated circuit device includes a leak detection circuit which can be realized by small pattern area provides voltage Vb through two transistors M1n and M2n, which are caused to be operative in the sub-threshold area without use of a resistor at the gate of a leak current detection transistor MLn. The leak current detection magnification does not become dependent upon power supply voltage and temperature. Thus, detection of the leakage current can be precisely carried out.
