ABSTRACT:
A delay circuit device having first and second delay circuits arrays so constructed that an output can be taken out from an arbitrary position of a signal transmission path, discriminating circuits receiving an output from two positions which divide the first delay circuit array into three portions, and three control circuits. The first and second delay circuit arrays are so arranged that the direction of signal transmission paths are opposite to each other. An output of the first delay circuit array is connected to an input of the second delay circuit array through the control circuits in the order from the position near to an input of the first delay circuit array and in the order from the position near to an output of the second delay circuit array. A first signal is supplied to the first delay circuit array, and whether or not the first signal is propagated to the output of the two positions is respectively latched in the discriminating circuits. When an arbitrary time has elapsed after the first signal is supplied, a second signal is supplied to not greater than four control circuits of the control circuits, in accordance with data latched in the discriminating circuits. The first signal on the first delay circuit array is transferred to the second delay circuit array, and the first signal on the first delay circuit array is removed. Thus, a clock having no phase difference from an external clock can be generated with a low current consumption, with a small number of periods, over a wide frequency range, and over a wide power supply voltage range.
