    摘要: A bias circuit includes a resistor in parallel with a voltage-drive bias circuit including a GaAs-HBT transistor. This configuration ensures that a current can be supplied from a reference voltage input terminal to the base terminal of a first transistor via the resistor in an idling state in which a voltage applied to the base terminal is lower than a voltage at which a second transistor operates, thereby enabling a desired amplifying operation while maintaining the idling current generally constant in a temperature range, even when the reference voltage is reduced to a value lower than twice the barrier voltage of the GaAs HBT.

    摘要: A multiplier core outputs a single-phase signal containing a frequency component having a frequency which is an even multiple of the frequency of input signals. A differential amplifier includes first and second nMOS transistors having respective source terminals connected to each other. The output signal from the multiplier core is inputted to the gate terminal of the first nMOS transistor, and the gate terminal of the second nMOS transistor is AC grounded. The differential amplifier differentially amplifies the signals inputted to the gate terminals of the first and second nMOS transistors to output a potential at the drain terminals of the first and second nMOS transistors as a differential signal. The output terminal of the multiplier core is connected through a series LC circuit to the source terminals of the first and second nMOS transistors.

    摘要: An integrated circuit device includes a power amplifier having an FET; a negative voltage generator for supplying a negative voltage to the power amplifier; a power supply terminal receiving a positive power supply voltage through an external switch and applying the positive power supply voltage to the negative voltage generator and, through an internal switch, to the power amplifier; and a negative voltage detector for detecting the negative voltage output from the negative voltage generator and sending a control signal to the internal switch so that the internal switch is closed when the output voltage from the negative voltage generator is lower than a threshold negative voltage and open when the output voltage is higher than the threshold negative voltage. It is not necessary to supply an external negative voltage as a gate bias voltage of the FET. Since the positive power voltage is applied to both the power amplifier and the negative voltage generator, an external power supply control circuit outputs only one control signal to control the external switch. It is not necessary to set a time interval from application of the power supply voltage to the negative voltage generator until application of the power supply voltage to the power amplifier in advance so that power dissipation is significantly reduced.
