摘要： PROBLEM TO BE SOLVED: To solve the following problems: costs are high since a booster circuit formed by a CMOS process requires transistors having both P, N polarities and hence a manufacturing process is complicated; and a sufficiently large voltage cannot be applied to the gate of a charge transfer switch when Vth is large due to variations in manufacture since a gate voltage is reduced by the threshold Vth while the gate voltage of the charge transfer switch is boosted, and switching-on resistance causes deterioration in circuit characteristics.
SOLUTION: A circuit is formed by an NMOS single-channel process. Two systems of booster circuits are provided to boost gate voltage of the transistor 307 for charge transfer. One boost circuit is used for boosting the gate voltage of the transistor 307 in advance, and the other is used for boosting further, thus achieving a 2-stage booster configuration.
