Claim:
1. A method comprising: supplying a first signal to an input terminal of a transistor switch, wherein the first signal comprises a first direct current component and a first alternating current component; at a first time, activating the transistor switch by supplying a second signal to a gate terminal of the transistor switch, wherein the second signal comprises a second direct current component and the first alternating current component, wherein a difference between the second direct current component and the first direct current component is sufficient to activate the transistor switch to allow the first signal to pass through a channel of the transistor switch to an output terminal of the transistor switch; and at a second time, deactivating the transistor switch by supplying a third signal to the gate terminal of the transistor switch, wherein the third signal comprises a third direct current component and the first alternating current component, wherein a difference between the third direct current component and the first direct current component is sufficient to deactivate the transistor switch to prevent the first signal from passing through the channel of the transistor switch to the output terminal of the transistor switch; wherein, while the first signal is being supplied to the input terminal of the transistor switch, substantially the only voltage difference between the first signal and the second signal is the difference between the second direct current component and the first direct current component and substantially the only voltage difference between the first signal and the third signal is the difference between the third direct current component and the first direct current component, thereby causing one or more characteristics of the channel of the transistor switch to remain substantially constant while the channel is allowing the first signal to pass.
