放大器
摘要：
本申请公开了一种放大器，包括至少一个放大元件(20a，25a)和用于以偏置电压偏置所述或每个放大元件的偏置电路(32a，32b)。偏置电路(32a，32b)适于改变偏置电压，使得所述或每个放大元件响应于偏置控制信号(4)通过阈值在开关工作模式和非开关工作模式之间切换。
摘要（英）：

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.
