description Circuits and methods for biasing power amplifiers. In some embodiments, a power amplifier circuit can include a transistor having and input and an output, and configured to amplify a signal. The power amplifier circuit can further include a bias circuit configured to provide a bias signal to the input of the transistor. The power amplifier circuit can further include a switchable feed circuit implemented between the bias circuit and the input of the transistor, and configured to provide a plurality of different resistance values for the bias signal between the bias circuit and the input of the transistor.
