摘要： A semiconductor package assembly may include a lead frame having a die bonding pad and plurality of leads coupled to the first die bonding pad. A vertical semiconductor device may be bonded to the die bonding pad. The device may have a conductive pad electrically connected to one lead through a first bond wire. An electrically isolated conductive trace may be formed from a layer of conductive material of the first semiconductor device. The conductive trace provides an electrically conductive path between the first bond wire and a second bond wire. The conductive path may either pass underneath a third bond wire thereby avoiding the third bond wire crossing another bond wire, or the conductive path may result in a reduced length for the first and second bond wires that is less than a predetermined maximum length.

摘要： A current limiting load switch for bridging supply Vss and load with a reference voltage VRdt dynamically generated by a VRdt-generator is proposed. It includes: A pair of power FET and sense FET interconnected in split-current configuration. The FET pair develops a load voltage while limiting load current Iload to a preset maximum Imax. The FET pair is sized to draw device currents Ipower and Is with RATIOI=Is/Ipower
摘要翻译：提出了一种用于桥接电源Vss和由VRdt发生器动态产生的参考电压VRdt的负载的限流负载开关。它包括：分流电流互连的一对功率FET和感测FET。 FET对产生负载电压，同时将负载电流Iload限制在预设的最大值Imax。 FET对的大小可以用RATIOI = Is / Ipower << 1来绘制器件电流Ipower和Is。感测FET高端端子通过检测电阻Rsense耦合到Vss，感测电压Vs = Is×Rsense。一个电流限制放大器，其输入连接到VRdt和Vs，并且输出控制FET对封闭限流反馈回路。 VRdt发生器动态地调整VRdt并发和补偿，这是由于感测FET操作转换引起的改变RATIOI的不良影响，从而消除了Imload以外的Iload的过渡过冲。

摘要： Multiple channel maps are embedded in a television transmission and the appropriate-channel corresponding to the particular television service used by the viewer is downloaded for use with the television receiver. Each channel map is accompanied by a channel map identifier which identifies the source of the television transmission and a geographic identifier. The source of a television transmission is automatically detected by monitoring the radio-frequency spectrum allocations of telecast stations. The geographic area identifier is determined by comparison with a user inputted geographic area identifier. The channel map having a channel map identifier corresponding to the detected television transmission source and the user inputted geographic area identifier is downloaded and stored for future use.
