摘要： Provided are a digitally controlled circulator and a radio frequency identification (RFID) reader having the circulator. A power splitter is composed of lumped elements and the values of the elements are digitally changed using switching means, in which the transmission loss of a signal is controlled according to whether the reader is in a transmission state or a reception state. Therefore, the loss can be minimized, and the circulator can be miniaturized and priced down by an integrated circuit (IC) semiconductor process and mounted in a mobile terminal such as a cellular phone.

摘要： Provided is a demodulator circuit allowing a tag or transponder to efficiently recover data of an input amplitude signal at very low power in a wireless communication system such as a radio frequency identification (RFID) system. The demodulator connects an output of a voltage multiplier to a low-current path by capacitive coupling, thereby recovering data. Therefore, data is recovered, at low power, from an input amplitude signal having a low modulation depth, and it is possible to increase a communication distance.

摘要： This invention relates to an outline font, and more particularly to a progressive renderable outline font and methods for transforming and rendering the same. Its purpose lies in supplying a progressively renderable Font which can be varied according to the quantity of the data composing the font. The Progressively Renderable Font has the function of controlling the display speed and the quality of the font. For example, if the hardware speed is relatively slow and a high quality font is not needed, only a part of the font data will be transmitted and displayed. On the contrary, if the hardware speed is relatively fast and high quality font is needed, gradually increased data will be transmitted and displayed. Therefore, a font can be transmitted and displayed using minimal data without sacrificing quality. On the other hand, in case of the environment, all the data can be transmitted and displayed so that the quality of the font can be fully realized.
摘要翻译：本发明涉及一种轮廓字体，更具体地说，涉及一种渐进式可渲染轮廓字体及其变换和渲染方法。其目的在于提供逐渐呈现的字体，该字体可以根据构成字体的数据量而变化。逐行渲染字体具有控制显示速度和字体质量的功能。例如，如果硬件速度相对较慢并且不需要高质量的字体，则只会传送和显示一部分字体数据。相反，如果硬件速度相对较快，需要高质量的字体，则会传输和显示逐渐增加的数据。因此，可以使用最少的数据来传输和显示字体而不牺牲质量。另一方面，在环境的情况下，可以发送和显示所有数据，从而可以充分实现字体的质量。

摘要： Provided is a digital circuit for a passive RFID tag. The digital circuit for the passive RFID tag includes a construction that is divided into blocks, which receive a command, analyze and execute the command, and generate a reply signal respectively, according to the flow of data. Thus, the digital circuit transmits a clock signal to each of the blocks at a rate optimized for the block such that the blocks sequentially operate without any additional controller. The digital circuit for the RFID tag is constructed such that the respective blocks operate at different points in time. This precludes any useless operation of hardware, thus reducing the entire power dissipation.
