Abstract
An amplifier, tuner, and method of amplification are provided. The amplifier has a pair of transistors. Each transistor has a control terminal and an output terminal disposed between the transistor and a power supply input. A first network is connected between each power supply input and output terminal. The first network contains a first resistor and a first switch connected in parallel with the first resistor. A second network is connected between the transistors. The second network contains a first and second combination. Each of the first and second combinations contains a second resistor and a second switch connected in parallel with the second resistor. The first and second combinations are connected by a third switch.
