    • A semiconductor device capable of wireless communication which has low power consumption in a step for decoding an encoded signal to obtain data is provided. The semiconductor device includes an antenna configured to convert received carrier waves into an AC signal, a rectifier circuit configured to rectify the AC signal into a DC voltage, a demodulation circuit configured to demodulate the AC signal into an encoded signal, an oscillator circuit configured to generate a clock signal having a certain frequency by supply of the DC voltage, a synchronizing circuit configured to generate a synchronized encoded signal by synchronizing the encoded signal obtained by demodulating the AC signal with the clock signal, a decoder circuit configured to decode the synchronized encoded signal into a decoded signal, and a register configured to store the decoded signal as a clock (referred to as a digital signal).
    • 提供了一种能够在用于解码编码信号以获得数据的步骤中具有低功耗的无线通信的半导体器件。 该半导体装置包括将接收的载波转换为交流信号的天线,被配置为将交流信号整流为直流电压的整流电路,被配置为将该交流信号解调为编码信号的解调电路, 通过提供DC电压产生具有一定频率的时钟信号;同步电路,被配置为通过将通过解调AC信号获得的编码信号与时钟信号同步来生成同步编码信号;解码器电路,被配置为对同步编码的 信号转换为解码信号,以及配置为将解码信号存储为时钟(称为数字信号)的寄存器。
