    摘要： Circuits and a method for tuning an integrated circuit (IC) are disclosed. The IC includes multiple programmable fuses coupled to a control block. The programmable fuses used may be one-time programmable (OTP) fuses. The control block reads settings or data stored in the programmable fuses. A tuning circuit coupled to the control block receives the delay transmitted by the control block. The tuning circuit allows tuning of the IC without changes to the fabrication mask. The tuning circuit may include delay chains to provide additional delay to the IC when needed and the delay in the tuning circuit is configured based on the delay value stored in the programmable fuses and transmitted by the control block.

    摘要： A circuit and methods for placing a circuit block on an integrated circuit (IC) are disclosed. An embodiment of the disclosed method includes dividing the IC into multiple regions based on pre-determined value. This pre-determined value may be a voltage drop value measured on specific regions on the IC. The performance requirement for the circuit block is determined and placed in one of the regions on the IC. In one embodiment, the placement of the circuit block is based on the performance requirement and the measured value at specific regions on the IC. The measured value may be a voltage drop value and a circuit block with a higher performance may be placed in a region with a lower voltage drop value.

    摘要： An inexpensive method and system for maintaining communication between fixed receivers on the earth surface having fixed antennas and inclined orbit geostationary satellites. In preferred embodiments the fixed antennas of each receiver are provided with more than one feed horn (such as three or more feed horns) each positioned to form a beam with its antenna in a slightly different direction from beams of the other feed horns in the north-south direction. An algorithm is developed based on the known daily swings of the inclined orbit geostationary satellite which determines which of the feed horns provides a beam providing the maximum signal from the satellite.
