摘要： A charge accumulation circuit having a structure in which a capacitor is divided into a plurality of pieces and the divided capacitors are connected in parallel through switches is provided. The charge accumulation circuit controls the switch provided between the capacitors and thus can dynamically vary electrostatic capacitance of the charge accumulation circuit which applies a voltage to a constant voltage circuit.

摘要： In a case where an ASK method is used for a communication method between a semiconductor device and a reader/writer, the amplitude of a radio signal is changed by data transmitted from the semiconductor device to the reader/writer when data is not transmitted from the reader/writer to the semiconductor device. Therefore, in some cases, the semiconductor device mistakes data transmitted from the semiconductor device itself for data transmitted from the reader/writer to the semiconductor device. The semiconductor device includes an antenna circuit, a transmission circuit, a reception circuit, and an arithmetic processing circuit. The antenna circuit transmits and receives a radio signal. The transmission circuit outputs to the reception circuit a signal showing whether or not the antenna circuit is transmitting the radio signal.
摘要翻译：在使用ASK方式进行半导体装置与读取器/写入器之间的通信方式的情况下，通过从半导体装置发送到读取器/写入器的数据，无线信号的振幅由数据不从读取器/写入器到半导体器件。因此，在某些情况下，半导体器件将从半导体器件本身发送的数据错误地从读取器/写入器发送到半导体器件的数据。半导体器件包括天线电路，发送电路，接收电路和运算处理电路。天线电路发送和接收无线电信号。发送电路向接收电路输出表示天线电路是否正在发送无线信号的信号。
