Abstract
An amplifier comprising at least one amplifying element (20a, 25a) and a biasing circuit (32a, 32b) for biasing the or each amplifying element with a bias voltage is disclosed. The biasing circuit (32a, 32b) is adapted to vary the bias voltage such that the or each amplifying element switches between non-switching and switching modes of operation in response to a bias control signal (4) passing through a threshold value.
