摘要: According to one embodiment, a power supply circuit includes a power switch section, an error amplifier, a wiring and a reset switch section. The error amplifier has one input portion connected to the output terminal, the other input portion and an output portion. The error amplifier outputs the control potential via the output portion to make the resistance of the power switch section high so that potential applied to the one input portion is high to potential applied to the other input portion. The wiring connects a reference terminal to the other input portion. In addition, the reset switch section is configured to isolate the wiring from a baseline potential when the input terminal is supplied with a potential, and to connect the wiring to the baseline potential when the input terminal is not supplied with the potential.

摘要: According to one embodiment, a semiconductor switch includes a power supply circuit, a control circuit and a switch circuit. The power supply circuit includes an internal potential generator connected to a power supply, and a first transistor connected between an input and an output of the internal potential generator. The internal potential generator generates a first potential higher than an input potential. The first transistor is turned on when the first potential becomes lower than the input potential and has a threshold voltage being set so as to keep the first potential not lower than the input potential. The control circuit is configured to receive the first potential to output a high-level or low-level control signal. The switch circuit is configured to receive an input of the control signal to switch connection between terminals.

摘要: Optical signals inputted to input ports are split in half by 1×2 optical splitters respectively and the resulting signals are inputted to the input terminals of an optical matrix switch. The optical matrix switch switches between the routes of the individual optical signals and outputs the signal at any of the output ports. This enables the optical signal from the same input port to be outputted at two different output ports, which makes it possible to effect “bridge” at the time of protection switching.
