Title: Semiconductor integrated circuit device
Inventor: MATSUURA NOBUMI
IPC: H03K19/00
Filed: 1987-07-24
Abstract: PURPOSE:To improve an operation margin against an input signal level by canceling the change of the conductance of an FET, provided between an output node and a power source voltage, by the FET the gate of which the power source voltage is inputted to. CONSTITUTION:When the power source voltage Vcc comes higher, the gate source voltage of the FET Q1 of an input circuit IC1 comes larger, and the conductance of it comes larger as well, and the logical threshold level of the input circuit IC1 is apt to ascend. But, in company with the ascent of the voltage Vcc, the gate source voltage of the FET Q9, the gate of which is connected of the voltage Vcc, comes larger, and the conductance of it comes larger. Here, because the rate of the change of the conductance of the FET Q9, due to the fluctuation of the voltage Vcc, is designed so as to be the same as the rate of the change of the conductance of the FET Q1, the influence of the FET Q1, due to the change of the conductance is canceled, and the logical threshold level of the input circuit IC1 comes less dependent on the power source voltage.
