    Abstract: A drive circuit for supplying a constant drive current to the anode terminal of a semiconductor light emitting device (7), includes a current supply source (10) connected to the anode terminal for supplying a bias current to the semiconductor light emitting device. Since the drive circuit is formed so as to supply the bias current to the anode terminal of the semiconductor light emitting device, a charge current for charging a conjunction capacitance can be reduced independently on the time period of turning off the semiconductor light emitting device. As a result, a spike noise can be removed in the laser current waveform at its rise-up part, and a reduction of its rise-up speed can be restricted, both of which are due to a dependent upon the time period of turning off the semiconductor device.

    Abstract: A reduction in circuit size, an increase in operation speed, and a reduction in power consumption can be attained by a semiconductor device, in which capacitors (202) are connected to multiple input terminals (IN-1 to IN-n) through switch (203), one terminal (b) of each capacitor is commonly connected, and the common connection terminal is connected to a sense amplifier (205), including a reset (207) at a floating point which is the contact (b) between the common connection terminal of the capacitors and the input of the sense amplifier. In addition, an increase in yield can be realized by reducing the manufacturing cost.
