    摘要: According to one embodiment, a transmission system includes a transmitter, and a receiver. The transmitter includes one or a plurality of light sources, a modulator, a first driver, a display, and a second driver. The one or a plurality of light sources is configured to emit a visible light whose light amount corresponds to a first drive signal. The modulator is configured to, according to transmission data to be transmitted from the transmitter to the receiver, modulate a first luminance signal indicative of an amount of the light the light source is configured to emit, to generate a second luminance signal. The first driver is configured to generate the first drive signal based on the second luminance signal. A mean of the second luminance signal during one frame in the input video signal is substantially equal to a value of the first luminance signal in the frame.

    摘要: A semiconductor integrated circuit device constituting an inverting amplifier employs a cascode current source as a current source. In the semiconductor integrated circuit device, a high-potential-side transistor of the cascode current source and a low-potential-side transistor constituting an amplification portion are shared. The configuration can not only make an output impedance of the cascode current source high and improve current source characteristics but also make a minimum potential at a minimum potential point of the amplification portion low and ensure a sufficient power supply voltage margin.
