Abstract
A driver circuit generates two control signals that change from low to high as an input signal changes from high to low, and change from high to low as the input signal changes from low to high. The driver circuit also generates another two control signals that change from high to low as the input signal changes from high to low, and change from low to high as the input signal changes from low to high. The driver circuit applies these four control signals to gate terminals of four MOS transistors. Timings of logical level changes of these four control signals are controlled so as to generate a period in which the four MOS transistors are simultaneously turned on or off.
