  • Patent number: 7710211
    Abstract: An injection-locked frequency divider includes a signal injection circuit and colpitts VCO. The signal injection circuit is for injecting an injection signal. The colpitts VCO includes first and second transistors, first and second LC tank circuits and a cross-coupled transistor pair. The first terminals of the first and second transistors receive the injection signal. The first and second LC tank circuits are for determining resonance frequency of an oscillation signal of the colpitts VCO. The cross-coupled transistor pair includes third and fourth transistors. The control terminals of the third and fourth transistors are respectively coupled to first terminals of the fourth and third transistors. The first terminals of the third and fourth transistors are respectively coupled to a first terminal or control terminal of the first and second transistors for providing an equivalent negative resistance. The injection signal and oscillation signal are mixed in frequency to generate differential output signals.

  • Publication number: 20100030853
    Abstract: A desktop sharing and remote control system where a server and a client are connected by a USB cable. Either the server or the client includes an ASIC/CPLD/FPGA which is a PC-to-PC USB connection bridge. The ASIC/CPLD/FPGA enumerates a first standard USB mass storage device to the server and a second standard USB mass storage device to the client. The server executes a server side application program to obtain video data representing its desktop images and transmits the video data to the first emulated mass storage device, and to receive user input device data from the first mass storage device and apply them to control the server. The client executes a client side application program to obtain keyboard and mouse data and transmits the data to the second emulated mass storage device, and receive video data from the second mass storage device and applies it to a display device.
