Abstract:
A linear amplifier is provided to have higher efficiency for an envelope tracking modulator. In one embodiment, a first stage amplifier circuit can be simply operated in a high gain mode or a high bandwidth mode for different applications, without using large chip area. In another embodiment, an output stage has a cascode structure whose dynamic range is controlled according to a voltage level of a supply voltage, to make a core device within the output stage have better protection and suitable dynamic range.

Claim (Index 20):
The linear amplifier of  claim 19 , wherein the output stage further comprises:\n an operational amplifier having a first input terminal, a second input terminal and an output terminal, wherein the first input terminal is coupled to the source electrode of the first buffer transistor, the second input terminal is coupled to the reference voltage; and a switch, for selectively connecting the gate electrode of the first buffer transistor to the output terminal of the operational amplifier or to the ground voltage by referring to the level of the supply voltage.
