Abstract
A driver circuit comprising (i) a pair of complementary MOS (CMOS) transistors connected in series and receiving an identical input signal, and (ii) a pair of control transistors changing a threshold voltage state of each of the pair of CMOS transistors by applying a plurality of voltages to a body terminal of each of the pair of CMOS transistors depending upon the ON/OFF state of each of the pair of CMOS transistors. Such a driver circuit is capable of reconciling a high-speed operation with a low power consumption under low power supply voltage conditions.
