Provided is a semiconductor device for wireless communication which achieves a reduction in leakage power and allows an improvement in power efficiency. For example, to external terminals, an antenna driver section (ADRV) for driving an antenna (ANT) and a rectifying section (RECT) for rectifying input power from the antenna are coupled. The antenna driver section includes pull-up PMOS transistors and pull-down NMOS transistors. In the rectifying section (RECT), a power supply voltage generated by a full-wave rectifying circuit (FWRCT) is boosted by a voltage boosting circuit (UPC). For example, when a supply of a power supply voltage from a battery is stopped, a power supply voltage resulting from the boosting by the voltage boosting circuit (UPC) is supplied to the bulk of each of the pull-up PMOS transistors. |
