摘要： In a PLL circuit, a voltage controlled oscillator 4 has two voltage-current conversion circuits 40 and 41 and a selection circuit 42 for selecting an output of either one of the voltage-current conversion circuits 40 and 41. The output of the voltage-current conversion circuit selected by the selection circuit 42 is inputted to a current controlled oscillator 45. The one voltage-current conversion circuit 41 has an input thereof connected to an output of a loop filter 3, while the other voltage-current conversion circuit 40 has an input thereof connected to an input terminal 8 for evaluating the oscillation characteristics of the voltage controlled oscillator 4. As a result, time-varying fluctuations in the voltage of the loop filter resulting from a structure in which the input terminal for evaluating the oscillation characteristics of the voltage controlled oscillator is connected to the loop filter via a switch and time-varying fluctuations in the output frequency of the PLL circuit are effectively suppressed.

摘要： A current mirror circuit 10 is formed to have a current ratio (a transistor size ratio) of 1:m. As well, respective pairs of nMOS transistors MN1, MN3 and nMOS transistors MN2, MN4 are formed to have a current ratio of 1:m. Two currents output from the current mirror circuit 10 are each distributed to two. The distributed currents flowing in the nMOS transistors MN2, MN4 are added and are then allowed to flow into one resistor R2. Hence, for the resistor R2, only one resistor in which current of double flows suffices when m=1, for example. This effortlessly reduces the necessary resistance to one fourth.

摘要： In a PLL which does not include a loop filter, an additional circuit for subjecting a voltage-controlled oscillator to a burn-in test with an appropriate oscillation frequency is realized by a less circuit configuration.A gate terminal of a diode-connected transistor (13) which has the same polarity as a voltage-to-current conversion transistor (11) in a voltage-controlled oscillator (10) is connected to a gate terminal of the transistor (11) through a switch (12a), and a current supply (14) is connected to a drain terminal of the transistor (13). By appropriately controlling the current value supplied from the current supply (14) and the size ratio between the transistor (11) and the transistor (13), a current required for performing a burn-in test can be supplied to a ring oscillator in the voltage-controlled oscillator (10).

摘要： In a touch panel capable of detecting the coordinates of two pressed-down points individually at the same time, the coordinates detected while one point is pressed are stored and, if a second point is subsequently pressed, the stored coordinates of a first point are used to identify the coordinates closer to the stored coordinates as the first point and the coordinates of another detected point as the second point, thereby identifying an order in which the two points are pressed. Thereafter, what mouse operation has been executed at the coordinates of the first point is detected based on a positional relation between the coordinates of the first point and the coordinates of the second point, and a result of the detection is output to an application operable through a graphical user interface.
