  • Patent number: 9887763
    Abstract: A satellite signal reception device includes: a local signal generator that generates a signal while switching between a signal having a first local frequency corresponding to a first positioning satellite signal and a signal having a second local frequency corresponding to a second positioning satellite signal based on a reference clock signal; and a frequency converter that converts a reception signal of the first positioning satellite signal into a first intermediate frequency signal by multiplying the reception signal of the first positioning satellite signal by the signal having the first local frequency, and converts a reception signal of the second positioning satellite signal into a second intermediate frequency signal of which at least a part of a converted frequency band is in common with the first intermediate frequency signal multiplying the reception signal of the second positioning satellite signal by the signal having the second local frequency.

  • Patent number: 9013234
    Abstract: A transconductance adjustment circuit includes a reference signal generation circuit that outputs a first signal and a second signal that is different by 90 degrees in phase from the first signal, a replica circuit to which the first signal and the second signal are input and which generates a first output signal and a second output signal, and an adjustment signal generation circuit that outputs a transconductance adjustment signal with respect to the adjustment-targeted circuit and the replica circuit. The reference signal generation circuit generates the first signal and the second signal that change in voltage at between a first voltage level and a second voltage level, based on a clock signal, and outputs the generated first and second signals with respect to the replica circuit.

  • Publication number: 20130301753
    Abstract: A circuit device includes a communication circuit that includes at least one of a reception circuit and a transmission circuit, and an adjustment signal generating circuit that outputs an adjustment signal which adjusts a transconductance of an adjustment target circuit included in the communication circuit. The adjustment signal generating circuit performs a generation process of the adjustment signal, accumulates charge corresponding to the generated adjustment signal in a capacitor, and outputs the adjustment signal based on the charge accumulated in the capacitor to the adjustment target circuit.

  • Patent number: 5719592
    Abstract: A microcode-controlled video display controller achieves special functions such as enlargement, reduction, and rotation by performing various transformations on the display screen coordinates in order to generate addresses for accessing a display memory containing image formation data. The transformed addresses are used to fetch display data and information in an order other than the order in which the data and information were originally stored in the display memory.
