Abstract
A wireless type data transmission device (data carrier) has a receiver for receiving electric wave transmitted from a reader-writer, a rectifier for rectifying the received electric wave to generate a first voltage, and a booster for boosting the first voltage to produce a second voltage, which is higher than the first voltage, to drive an internal circuit of the wireless type data transmission device.
