摘要： To realize a driving circuit and a charging pump booster circuit utilizing said [driving circuit] capable of reducing the power consumption and the noise generated during switching. Transistors Q1 and Q2 are controlled based on a control signal input into an input terminal T in , and a charge/discharge current is output to an output terminal T out . The base of a transistor Q5, having almost the same characteristics as those of the transistor Q1, is connected to the base of the transistor Q1 in order to have the transistor Q5 generate a current corresponding to the turning on/off of the transistor Q1, and the current from said transistor Q5 is reflected toward a resistance element R1 by means of a current mirror circuit comprising transistors Q6 and Q7, so that base voltage of the transistor Q2 can be set lower while the transistor Q1 is on in order to hold the transistor Q2 to the OFF status. As a result, leak-through current in the transistors Q1 and Q2 can be reduced and switching noises created by said leak-through current can be restrained.
