  • Amplifier with pass-through mode
    Patent number: 8487698
    Abstract: In an amplifier with pass-through mode of the present invention, in a pass-through mode, a signal transmission transistor and a bias control transistor are turned ON and a voltage of an output terminal is maintained in a ground potential via the bias control transistor and a resistor. Thus, a power supply voltage is applied to a control terminal of the signal transmission transistor and one main terminal of the signal transmission transistor is maintained in a ground potential. Therefore, an ON-resistance of the signal transmission transistor is decreased to a minimum level.
