摘要: An object is to provide a demodulation circuit having a sufficient demodulation ability. Another object is to provide an RFID tag which uses a demodulation circuit having a sufficient demodulation ability. A material which enables a reverse current to be small enough, for example, an oxide semiconductor material, which is a wide bandgap semiconductor, is used in part of a transistor included in a demodulation circuit. By using the semiconductor material which enables a reverse current of a transistor to be small enough, a sufficient demodulation ability can be secured even when an electromagnetic wave having a high amplitude is received.

摘要: 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.

摘要: It is an object to provide a display having high visibility and a transflective type liquid crystal display device having a reflection electrode having a concavo-convex structure formed without especially increasing the process. During manufacturing a transflective liquid crystal display device, a reflection electrode of a plurality of irregularly arranged island-like patterns and a transparent electrode of a transparent conductive film are layered in forming an electrode having transparent and reflection electrodes thereby having a concavo-convex form to enhance the scattering ability of light and hence the visibility of display. Furthermore, because the plurality of irregularly arranged island-like patterns can be formed simultaneous with an interconnection, a concavo-convex structure can be formed during the manufacturing process without especially increasing the patterning process only for forming a concavo-convex structure. It is accordingly possible to greatly reduce cost and improve productivity.
