Abstract
An integrated amplifier device includes a main amplifier configured to be coupled to an input source. A replica amplifier is coupled to the main amplifier to provide a bias to the main amplifier. A transconductance biasing cell to the main amplifier and the replica amplifier. The transconductance biasing cell is configured to bias both the main amplifier and the replica amplifier. A method of making an integrated amplifier device is also disclosed.
