  • Thermal control system and method for operating an integrated circuit
    Patent number: 8217707
    Abstract: According to one embodiment, a system and method for operating an Integrated Circuit (IC) includes inputting power to the IC in bursts, sensing an IC temperature using a temperature sensor, operating the IC by controlling the power to be outputted by the IC during the burst in dependence on the sensed IC temperature compared to a reference IC temperature using a controller, wherein the IC temperature is obtained at a predetermined moment prior to a start of the burst, and the IC is operated by setting an allowable power to be outputted by the IC prior to the start of the burst.

  • OPERATING AN INTEGRATED CIRCUIT
    Publication number: 20100066432
    Abstract: The invention relates to operating an Integrated Circuit (IC). The present inventor has assessed that IC systems may suffer from limited lifetime e.g. due to overheating. Among others the invention discloses a method of operating an IC (304), the method comprising inputting power to the IC in bursts (102, 108, 116), sensing (118) an IC temperature using a temperature sensor (306), operating the IC by controlling the power (316) to be outputted by the IC during a burst (108, 116) in dependence of the sensed IC temperature compared to a reference IC temperature (318) using a controller (202), wherein the IC temperature is obtained at a predetermined moment prior to a start (612) of a burst (108, 616), and the IC is operated by setting (120) an allowable power (106) to be outputted by the IC prior to the start of said burst (108).

  • Dual Gilbert Cell Mixer with Offset Cancellation
    Publication number: 20090149149
    Abstract: An electronic device includes a first mixer portion having a first stage and a second stage, and a second mixer portion having a first stage and a second stage. A first electrical path is coupled to the first mixer portion and the second mixer portion, and a second electrical path is coupled to the first mixer portion and the second mixer portion. The first mixer portion is adapted to receive a first input signal on the first stage and a second input signal on the second stage. The second mixer portion is adapted to receive the second input signal on the first stage and the first input signal on the second stage.
