Abstract: A power amplifier apparatus is provided. The power amplifier apparatus includes a number of multi-stage power amplifiers and a bias circuit configured to generate a number of bias signals (e.g., bias current or bias voltage) to control (e.g., activate or deactivate) the multi-stage power amplifiers. In examples disclosed herein, only one of the multi-stage power amplifiers is activated at a given time. In this regard, the bias circuit can generate the bias signals to collectively activate one of the multi-stage power amplifiers, while deactivating the rest of the multi-stage power amplifiers. As such, it may be possible to control a larger number of power amplifier stages based on a smaller number of bias signals. As a result, it may be possible to eliminate a biasing bump pad(s) from the power amplifier apparatus, thus helping to reduce the footprint and cost of the power amplifier apparatus.

Abstract: Bias circuitry is disclosed with a bias drive device having a first current terminal coupled to a voltage supply node, a bias control terminal coupled to a control node, and a second current terminal coupled to a bias output node. An impedance control device has a third current terminal and an impedance control terminal that are coupled together and a fourth current terminal coupled to ground. An output impedance resistor is coupled between the third current terminal and the bias output node. A pull-down device is coupled between the bias output node and the fixed voltage node, wherein a higher voltage applied to the control node sets an output impedance at the bias output node to approximately a lower impedance of the pull-down device and a lower voltage applied to the control node sets the output impedance to approximately the resistance of the output impedance resistor.
