Title: Oscillator circuit having reduced phase noise
Inventor: LEE JEROLD
IPC: H03B5/12
Filed: 2001-09-12
Granted: 2003-10-11
Abstract: The present invention, generally speaking, allows for a substantial reduction in oscillator phase noise by modifying the transfer function of a portion of the oscillator, e.g., by adding a zero to the transfer function. Modifying the transfer function reduces the open-loop gain of the oscillator but achieves a desired phase compensation, allowing the oscillator to be operated at the resonance of the resonator instead of off resonance. In an exemplary embodiment, the transfer function is modified by choosing a capacitance value such that, instead of operating as a bypass at the frequency of interest, adds a zero to the transfer function of the oscillator and causes a change in frequency characteristics, achieving an increase in the effective Q of the oscillator. This increase in effective Q translates directly into reduced phase noise. Phase noise improvement in the range of 3dB has been demonstrated.

Title: Method of using non-conductive adhesive to bond integrated circuit with board and its assembling structure
Inventor: HSIEH YU-TE
IPC: H01L23/28
Filed: 2001-10-26
Granted: 2002-10-01
Abstract: The present invention is related to the method of using non-conductive adhesive to bond integrated circuit (IC) with board and its assembling structure. The purpose of the non-conductive adhesive, which contains high hardness and nonconductive filler, is to lower thermal expansion coefficient of the adhesive and to decrease the difference of thermal expansion coefficients among the adhesive, the board and the chip so as to make the samples capable of passing the reliability test. The hardness of the filler is at least two times larger than that of the metallic bump at the bonding position such that the filler can be embedded into the metallic bump surface after it is thermally pressed and bonded. Therefore, the bump on the chip can directly contact the bond pad of the board to generate circuit conduction. The nonconductive filler contained in the adhesive can prevent short circuit phenomenon from being generated in between the bumps on the IC chip and increase the density of bonding technique. If the concentration of the nonconductive filler in the nonconductive adhesive is too low, the thermal expansion coefficient of the adhesive can not be decreased; if the concentration is too high, the conduction effect between the bump of the chip and the bond pad of the board is would be affected.

Title: Time multiplexed transmission scheme for a spread spectrum communication system
Inventor: BENDER PAUL
IPC: H04B7/26
Filed: 2002-03-18
Granted: 2003-12-01
Abstract: A ""time multiplexed"" transmission scheme capable of reducing the amount of interference from other cells operated at the same frequency band. Each cell in a system transmits in designated time intervals (e.g., time slots) during which other interfering cells may be prevented from transmitting. By temporarily ""blanking"" transmissions from interfering cells during the designated time slots, the amount of interference from these cells is reduced. The improved signal quality may support transmission at a desired or higher data rate, which may not be possible without cell blanking. In one variant, transmissions from the cells are staggered over different time slots. A set of one or more cells may be designated to transmit in each of a number of slot phases. The cells transmit in a staggered manner on these phases to reduce interference. The transmission scheme may be used for a various channel types (e.g., a control channel) and applications.

Abstract: The communication network comprises a device of a first type (1) furnished with a source of data to be broadcast over the network and at least one device of a second type (2) intended to receive the said data. The symmetric key management process comprises the following steps: the source device (1) determines a first symmetric key (Kc) and transmits it securely (E1{PUB2}(Kc)) to at least one receiver device (2); a receiver device (2) receives the first symmetric key (Kc), encrypts it (E2) with the aid of a second symmetric key (Kn), known to the receiver devices (2) of the network and transmits it to the source device; the source device (1) recovers the encryption (E2{Kn}(Kc)) of the first symmetric key (Kc) and stores it. Before transmitting the data (CW) to at least one reception device (2), the source device (1) encrypts (E3) these data with the aid of the first symmetric key (Kc), then it transmits these encrypted data (E3{Kc}(CW)), accompanied by the first encrypted symmetric key (E2{Kn}(Kc)), to at least one receiver device (2). The receiver device (2) decrypts the first symmetric key (Kc) with the aid of the second key (Kn) which it possesses, then it decrypts the encrypted data with the aid of the first symmetric key thus recovered. The invention also pertains to devices for implementing the process.
