摘要： A tamper resistant electronic tag that wirelessly receives and transmits unique subscriber information to and from a transceiver so that financial transactions can occur quickly and seamlessly. In a preferred embodiment, the tag works in conjunction with a roadway toll booth and is mounted onto a flat interior surface of a vehicle, where it can receive and transmit electronic information to and from a toll booth. That allows a driver to pay the toll fee without having to stop his vehicle. The electronic tag includes a plastic protective card for carrying a circuit. The circuit includes an integrated circuit that is adhesively attached to the protective card. The protective card and circuit are then attached to the flat surface. When the protective card is removed, the integrated circuit is pulled off with the protective card while the rest of the circuit remains attached to the flat surface, thereby severing the circuit, and rendering it inoperable. This prevents the unwanted tampering and unauthorized use of the electronic tag.

摘要： A digital differential receiver IC that rejects the inter-symbol interference (ISI) that is imposed upon differential digital signals when long runs of a digital state (0 or 1) are transmitted over long cables. The ISI-rejecting differential receiver IC is implemented in either bipolar technology (n-p-n or p-n-p) or in insulated gate FET technology (p-channel or n-channel). The primary differential pair of transistors is connected to a secondary differential pair of transistors through a filter network so that a high pass “shelf” filter transfer function exists between the differential input signals and the output signals. This transfer function mitigates ISI by reducing the gain for long runs of a digital state (low frequencies) and enhancing the gain for the state transition edges (high frequencies).
摘要翻译：数字差分接收器IC，当数字状态（0或1）的长时间运行通过长电缆传输时，拒绝对差分数字信号施加的符号间干扰（ISI）。 ISI抑制差分接收器IC采用双极技术（n-p-n或p-n-p）或绝缘栅FET技术（p沟道或n沟道）实现。主差分对晶体管通过滤波器网络连接到次级差分晶体管对，使得差分输入信号和输出信号之间存在高通“搁置”滤波器传递函数。该传递函数通过减少长时间运行的数字状态（低频）并增强状态转换边缘（高频）的增益来减轻ISI。
