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 9):
The linear amplifier of  claim 8 , wherein the differential driving signal comprises a first driving signal and a second driving signal, and the output stage comprises:\n a first cascode circuit, comprising:\n a first output transistor, coupled to the supply voltage, for receiving the first driving signal; and \n a first buffer transistor, coupled between the first output transistor and an output node of the output stage; and \n a second cascode circuit, comprising:\n a second output transistor, coupled to a ground voltage, for receiving the second driving signal; and \n a second buffer transistor, coupled between the second output transistor and the output node of the output stage.
