    • The present invention relates to a semiconductor integrated circuit and a wireless communication apparatus that can be reduced in size without deteriorating a receiving sensitivity and a transmission efficiency. Communication with an external reader/writer and an external non-contact IC card is carried out through a common antenna 211. The signal received from the external reader/writer or the external non-contact IC card through the antenna is supplied to an ASK demodulation circuit 149 and demodulated. The signal received from the external reader/writer is full-wave rectified and smoothed by an full-wave rectification and smoothing circuit composed of diodes 231, 232 and a capacitor 233, and the power obtained from the full-wave rectified and smoothed signal is supplied to respective units of a semiconductor integrated circuit 101. The present invention can be applied to a mobile phone.
    • 本发明涉及可以在不降低接收灵敏度和传输效率的情况下减小尺寸的半导体集成电路和无线通信装置。 通过公共天线211进行与外部读写器和外部非接触IC卡的通信。通过天线从外部读写器或外部非接触IC卡接收的信号被提供给ASK解调 电路149并进行解调。 从外部读写器接收的信号由二极管231,232和电容器233构成的全波整流平滑电路进行全波整流和平滑处理,从全波整流平滑信号得到的功率为 提供给半导体集成电路101的各个单元。本发明可以应用于移动电话。
