ABSTRACT:
A multistage RF amplifier amplifies RF signals used for communication in a WLAN communications system. The multistage RF amplifier comprises a first amplifier circuit coupled to a second amplifier circuit to maximize amplification. A common mode of the first amplifier circuit is coupled to a common mode of the second amplifier circuit to provide a voltage offset. The voltage offset counters voltage changes due to oscillations in the first amplifier circuit, thereby reducing interference from the multistage RF amplifier.
