SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To reduce current consumption in a semiconductor integrated circuit using a fine MOS transistor. SOLUTION: While both first and second MOS transistors are turned off (T1=VC and I1=VC), a voltage between the gate and source of the first MOS transistor is the inverse polarity of a voltage between the gate and source of the first MOS transistor while the first MOS transistor is turned on. Therefore, the first MOS transistor is turned into strong OFF state and a sub- threshold current is remarkably decreased.
