摘要 |
<p>The gate-width ratio between a NMOS transistor (1) and PMOS transistors (2, 3) constructing an initial inverter stage of a voltage converting circuit is set in such a manner that the threshold voltage of the initial inverter becomes a voltage at which an inversion is possible, this voltage being less than one-half the power-supply voltage (VHT) of the voltage converting circuit and, moreover, less than the power-supply voltage (Vdd) of a logic circuit. <IMAGE></p> |
