SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE AND ELECTRONIC EQUIPMENT

摘要

PURPOSE: To provide a semiconductor integrated circuit device or an electronic equipment having a step-up circuit which has high efficiency and a low cost by connecting a plurality of diode-connected MOSFETs in series, and improving the step-up circuit which inputs an input signal to the node of a MOSFET via a capacitor. CONSTITUTION: The threshold values VtM0 to VtMn of the MOSFETs M0 to Mn of a step-up circuit and the capacitance values CC1 to CCn of capacitance elements C1 to Cn are altered. Or, a signal step-up circuit for stepping up the peak values of clock signalsΦ,Φ* of the input signals to be input to the step-up circuit is added.
