    摘要: The object of the invention is to provide a frequency generator which is composed of an oscillator and a frequency doubler and in which difference in amplitude between differential outputs of the frequency doubler can be equalized at low power consumption without adjustment. To achieve the object, the amplitude of differential outputs of the frequency doubler is detected and the delay time of a variable delay circuit is controlled. Owing to this configuration, in case a frequency of the oscillator varies or in case delay time by the delay circuit used in the frequency doubler varies by process variation and others even if the frequency is fixed, the amplitude of the differential outputs of the frequency doubler can be also equalized in the frequency generator.

    摘要: An optical receiver generates a voltage signal having a predetermined swing from a current signal, and feeds the voltage signal to a decision circuit. An optical receiving element receives the input optical signal, converts the optical signal to a current signal, and provides the current signal to a preamplifier, which converts the input current signal into a voltage signal. The voltage signal is input to an amplifier having a limiting function, which linearly amplifies the voltage signal when the swing of the voltage signal is smaller than a predetermined value, and limitedly amplifies the voltage signal when the voltage signal is greater than the predetermined value. An automatic-gain-control amplifier receives the output from the amplifier with the limiting function, and amplifies the input voltage signal to a voltage signal having a constant swing. The decision circuit receives the output of the automatic-gain-control amplifier and decides the binary nature of the voltage, and thus of the input optical signal.
