摘要： In response to changes in an input binary digital signal, a 3rd order cosine pulse waveform, which, when it is changed in the increasing direction, has “0” level in a first period of T/12 (T corresponding to one-half cycle of the binary digital signal), is changed as a waveform of (h/2)(1+cos(3πt/T)+π/4) in the next period of 4T/12 (−5T/12≦t≦−T/12) and has an h (constant) level in the remaining period of T/12, and when it is changed in the reducing direction, has the h level in the first period of T/12, is changed as a waveform of (h/2)(1+cos(3πt/T)−π/4) in the next period of 4T/12 (T/12≦t≦5T/12) and also has “0” level in the remaining period of T/12. By using this pulse wave, a flat part is generated in a time width of T/12 with respect to a judgment point. It is thus possible to improve the immunity to the effects of digital signal jitter, obtain change judgment with a sole single pulse and reduce the circuit scale and the power consumption.

摘要： In a frequency-dividing circuit for producing an output having a frequency half that of its input, a pair of terminals of a latch circuit are connected to input terminals of a pair of amplify/delay means, and are also connected to receive through a pair of transistors, the outputs of the amplify/delay means. A single-phase input signal is input to the control electrodes of the transistors to turn on and off the transistors. When the transistors are turned from off to on, the output states of the amplify/delay means are transferred through the transistors to invert the latch circuit, and the states of complementary terminals of the latch circuits are in turn transferred through the amplify/delay means to invert the output states of the outputs of the amplify/delay means. When the transistors are turned from on to off, no change occurs in the states of the circuit. In this way, the states of the circuit are inverted each time the transistors are turned from off to on. A frequency-divided output can therefore be derived at one of the outputs of the first and second amplify/delay means. Either one or both of the first and second inverters may be replaced by a NAND gate or a NOR gate for permitting reset of the circuit.

摘要： An InP semiconductor thin film is formed by a process in which an amorphous GaAs buffer layer having a good surface flatness, and then an amorphous InP buffer layer having a good surface flatness are formed on an Si substrate, and then an InP monocrystalline thin film is grown on the InP buffer layer. GaAs has a lattice constant intermediate between Si used as the substrate and InP, so the lattice mismatch is reduced.
