ABSTRACT:
It is an object of the present invention to prevent an error or malfunction such as nonresponse which is caused due to difference in pulse width in a semiconductor device capable of communicating data wirelessly. In a semiconductor device, a level shift circuit is provided between a data demodulation circuit and each circuit block where demodulated signals are outputted from the data demodulation circuit. In such a manner, voltage amplitude of the demodulated signal is made almost equal to that of the outputted signals from each circuit block. Accordingly, a pulse width of the demodulated signal is made almost equal to that of signals in each circuit block, or a pulse width of the demodulated signal is made almost equal to that of the outputted signals from each circuit block. Accordingly, it is possible to prevent an error or malfunction such as nonresponse which is caused due to difference in pulse width.
