    摘要: A semiconductor device for driving a light emitting element used in high speed optical communication. The semiconductor device comprises circuitry for delaying a clock signal and producing first and second delay signals. The second delay signal has a delay time different from that of the first delay signal. The first delay signal controls flip-flop circuitry which receives a data signal and outputs a signal indicative of the data signal. The first delay signal also controls a first latch circuit to receive the signal from the flip-flop circuitry and output a signal with the delay time of the first delay signal. The second delay signal controls a second latch circuit to receive the signal from the flip-flop circuitry and output a signal with the delay time of the second delay signal. The signals output from the first and second latch circuits are logically combined by logic circuitry. The logic circuitry is either AND or OR circuitry. The logic circuitry outputs the result of the combination to driving circuitry which provides the current to drive the light emitting element in accordance with the output of the logic circuitry.

    摘要: A current-switching type compound semiconductor logic circuit which is high in an operating speed and low in power consumption. Voltage stabilizing transistors (25,26) are provided to the logic circuit so that voltage signal which are in-phase with the gates of driving transistors (21,22) and has a mean electric potential higher than that of the same by a predetermined value is applied to the gate thereof. The voltage stabilizing transistors (25,26) act as a buffer to prevent electric potential of the driving transistors (21,22) from fluctuating. As a result, it is possible to secure stable outputs in which the distortion of a waveform or the fluctuation of a cross point due to a jitter is hardly generated.
