摘要： A method of placing delay units of a pulse delay circuit on a programmable logic device having logic cells in each of cell strings has a step of arranging each delay unit in one logic cell of the device such that the delay units are placed in respective specific cell strings aligned in a row direction and a step of serially connecting the delay units with one another as a straight delay line such that the delay units placed in the specific cell strings in the connecting order are aligned in the row direction. In the device, an inter-string transmission delay time on a line between two logic cells of different cell strings differs from an intra-string transmission delay time on a line between two logic cells of one cell string.

摘要： A physical quantity detecting is capable of easily adjusting sensitivity and an offset of a detected output without being increased in size. In a signal processor for driving a sensor element in which fixed electrodes are disposed on both sides of a movable electrode displaced in response to acceleration, a signal generator generates PWM signals PA and PB in which an invalid control period during which the fixed electrodes are both deenergized only during a period corresponding to data M3 stored in a memory, is, at a predetermined ratio, inserted into a valid control period during which the fixed electrodes are alternately energized and their energization ratio is controlled so that the movable electrode is placed in position. Since the sensitivity of the sensor element to the acceleration changes according to the length of the invalid control period which does not contribute to control of the position of the movable electrode, its sensitivity can be easily adjusted by simply changing the value set in the memory.

摘要： A ring oscillator for circulating pulse edges of two types therein includes an even number of inverting circuits connected in a ring. Each of the inverting circuits is operative to invert an input signal and output an inversion of the input signal. One of the inverting circuits is a first start inverting circuit which starts an operation of inverting an input signal in response to a first control signal applied from an external input. One of the inverting circuits except the first start inverting circuit and an inverting circuit immediately following the first start inverting circuit is a second start inverting circuit which starts an operation of inverting an input signal in response to a second control signal. A control signal inputting arrangement serves to input the second control signal to the second start inverting circuit during an interval from a first moment at which the first control signal is inputted into the first start inverting circuit and the first start inverting circuit starts the inverting operation to a second moment at which a pulse edge initially generated by the start of the inverting operation of the first start inverting circuit and travelling while being sequentially inverted by the inverting circuits enters the second start inverting circuit.
