  • Semiconductor device including a rectification circuit
    Patent number: 9881246
    Abstract: In a semiconductor device that generates a power supply voltage from an RF carrier signal received by an antenna through the use of a rectification circuit, rectification circuits, each including a plurality of capacitors and a plurality of diodes, are connected in multistage. The rectification circuits includes limiter circuits that are turned on at a voltage larger than an on-voltage of the diodes, clamp cathodes of the diodes at a first voltage. The limiter circuits and the diodes are connected in parallel between the capacitors connected to the antenna connection terminal and a node supplied reference potential VSS of the power supply voltage.
