  • Patent number: 8279570
    Abstract: An electrostatic discharge (ESD) circuit, adaptive to a radio frequency (RF) device, which includes a RF circuit coupled between a VDD power rail and a VSS power rail and having a RF I/O pad, includes an ESD clamp circuit coupled between a VDD power rail node and the VSS power rail node and a LC-tank structure coupled between the VDD power rail node and the VSS power rail node and to the RF I/O pad. The LC-tank structure includes a first ESD block between the VDD power rail node and the RF I/O pad, and a second ESD block between the VSS power rail node and the RF I/O pad. At least one of the first and second ESD blocks includes a pair of diodes coupled in parallel with each other and an inductor coupled in series with one of the pair of diodes.

  • Publication number: 20050271126
    Abstract: A high-speed transceiver apparatus is connected between a USB controller of a host and a peripheral device. The transceiver apparatus has a dual-port memory with a first data port and a second data port, a DMA unit providing a data transmission between the second data port and the peripheral device, and a processor controlling the data access of the dual-port memory for the peripheral device. When the USB controller of the host accesses the dual-port memory through the first data port, the processor commands the peripheral device to access the dual-port memory through the second data port. The DMA unit controls the data transmission between the dual-port memory and the peripheral device.
