Radio frequency amplifier with reduced intermodulation distortion |
摘要 |
Apparatus and methods of broadband amplification with high linearity and low power consumption are described. An apparatus configured to amplify a signal includes an input transistor and an output transistor coupled together in a cascode configuration with the input transistor defining an input of the amplifier and the output transistor defining an output of the amplifier. A feedback network is coupled between the input and the output and is characterized by an impedance of substantially zero resistance and non-zero reactance. A method of amplifying a signal is also described. An input signal is received at an input; the input signal is amplified to provide an output signal at an output; and the output signal is sampled at the input through a feedback network characterized by an impedance of substantially zero resistance and ion-zero reactance. A method of making an apparatus configured to amplify a signal is also described.
