    摘要: An operational amplifier including a pair of differential input transistors is provided with a feedback resistor switching circuit and a variable current source. When a loaded optical disk is a DVD-ROM, the feedback resistor switching circuit reduces a gain of the operational amplifier and the variable current source selects a large current (of, for example, 1 mA) as a common bias current supplied to the differential input transistors. When the loaded optical disk is a DVD-RAM with low reflectance and low recording/reproducing speed, the feedback resistor switching circuit enhances the gain of the operational amplifier and the variable current source selects a small current (of, for example, 0.5 mA) as the common bias current.

    摘要: A photo detector IC (PDIC) is connected with a flexible printed circuit board (FPC). A signal converted into a voltage through light-to-voltage conversion in the PDIC is connected with the drain of a field effect transistor (FET), while the source of the FET is connected to an output terminal. A signal from the output terminal is input into a signal processing board of the main body via the FPC serving as an equivalent circuit composed of a coil and a capacitor. The gate of the FET is connected with a variable voltage source. Peaking occurs due to inductor components and capacitance components of the FPC. However, by application of voltage to the variable voltage source, the gate voltage value of the FET is adjusted to be an optimal value, whereby the peaking is suppressed by the on-resistance of the FET.
