Abstract
In an optical disk system, a high-frequency laser diode modulator has been required to reduce the optical feedback noise. A GaAs multivibrator IC has been developed for this requirement. The IC includes a multivibrator, a buffered amplifier, and a laser driver. All these circuits are designed using the same common-drain configuration for monolithic integration in a chip size of 1.3*10 mm/sup 2/. The IC oscillates in the frequency range of 560+or-40 MHz with a power output range of 5+or-1 dBm. A noise reduction of over 6 dB was obtained by applying the IC to the optical disk system.<>Keywords
